ashnaBest ResponseYou've already chosen the best response.1
i don't understand .. what did you want me to do actually ?
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
question means one question. questions means more than one questions.. Leave it.

waterineyesBest ResponseYou've already chosen the best response.2
For fist part: Find the molecular mass of \(CO_2\)..
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
molecular mass , mass and molar mass excluding the ( g ) all the same ?
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
I will say not to go this way..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
See now you have studied What is Molar Mass.. Molar mass is mass of 1 mole of any substance. If that substance is CO2 then: Molar Mass is mass of 1 mole of CO2 So here basically you have to find Molar Mass.. For getting molar mass you will find the molecular mass of CO2 first same as you did for NaCl..
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
yeah okay .. so in the question we are asked to find the mass right ?
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
For atoms: we have atomic mass. For molecules we have molecular mass..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Yes.. Molar mass is nothing but mass only. Molar Mass is "Mass" of 1 mole of a substance in grams..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
According to the definition of molar mass: Molar mass is mass of 1 mole right ??
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
But you have to find for 0.5 mole.. This you got mass for 1 mole.. can you find? for 1 mole it is 44g for 0.5 or half it will be ??
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Think logically also.. For 1 it is 44g for half that is 0.5 is nothing but half of 1: for 0.5 it will be 44/2 = 22g. Getting ??
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
yea yea .. on second thinking i understood !
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
i forgot half of 1 is 0.5 !

Go for last part.. e) part
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
This I tell you later on..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
e part is same as a part. Just try that so that you will completely get it..
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
mass of 1 mole of CO2 = 44 g mass of 1.5 mole of CO2 = ? 44 * 1.5 / 1 = 66 g

Yes concept is right..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Dear there is H2SO4 not CO2...
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
okay let me do with H2SO4
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Do the same for H2SO4..

Atomic Mass of H is : 1 Atomic Mass of S is : 28 Atomic Mass of O is : 16..
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
mass of 1 mole of H2SO4 = 98 g mass of 1.5 mole of H2SO4 = x = 98 * 1.5 / 1 = 147 g
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
atomic mass of s = 32 or 28 ?
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
I think you are right..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
My mistake : Atomic Mass of Sulphur is 32..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Yes you have done that correctly: 98 + 49 = 147 g...
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Now we will do second part b)..
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
but i did that before right ?
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Yes somewhat wrong..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Sere have you remembered this: \[1 Mole (oxygen) = 6.023 \times 10^{23} \; Oxygen \; \; Molecules\]
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
then .. how to do ? are you trying ?
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Oh really very sorry.. You were doing it right
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
\[6.023 \times 10^{23} \implies 32g\] \[1 \implies \frac{32}{6.023 \times 10^{23}}\] \[6.023 \times 10^{21} \implies \frac{32}{6.023 \times 10^{232}} \times 6.023 \times 10^{21} = ??\]

liter or litre not sure with the spelling .. !
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Do you have answers with you for all of these??
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
or have your teacher given example of How for Liters we find the mass ??

ashnaBest ResponseYou've already chosen the best response.1
i guess the teacher has done this in class !
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
okay she's written something like 22.4 L .. What is that ?
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
I think I am getting that 22.4 part..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Can you wait for just few minutes. I am having breakfast now.. Till then check this: http://www.ausetute.com.au/moledefs.html
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
There check: Ideal Gas Volumes Part..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
An ideal gas has Volume = 22.4 L at STP..
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
So: 1 Mole of SO2 = 22.4 L 1L = 64/22.4 56.8 L = 64/22.4 * (56.8? Right ??

waterineyesBest ResponseYou've already chosen the best response.2
Can you do the solvation ??
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
Understood ?? How to find all ??
 one year ago

ashnaBest ResponseYou've already chosen the best response.1
okay now .. next question ?
 one year ago

waterineyesBest ResponseYou've already chosen the best response.2
I am gone.. New post please..
