Best ResponseYou've already chosen the best response.0See there your question is given like: 2g of a Substance is added to water... Can you tell me what is solute here and what is the solvent here ??

Best ResponseYou've already chosen the best response.0solvent is water and solute is that 2g substance .. correct ?

Best ResponseYou've already chosen the best response.0For finding molarity you need number of moles solute.. How will you find number of moles of solute because it is given in 2 grams.. ??

anonymous

Best ResponseYou've already chosen the best response.0For that there is a formula you will use that..

Best ResponseYou've already chosen the best response.0ah .. that previous one ?

Best ResponseYou've already chosen the best response.0derived from molarity .. ?

Best ResponseYou've already chosen the best response.0\[Number \; Of \; Moles = \frac{Grams \; Present}{Molecular \; Mass \; Of \; that \; Substance}\]

Best ResponseYou've already chosen the best response.0No no that one.. This one I have written above now..

Best ResponseYou've already chosen the best response.0how many formulas are there in this chapter ?

Best ResponseYou've already chosen the best response.0Now let us try to implement this formula on a question so that you can understand it properly. There are as many formulas as there are hairs on your head.. Ha ha ha..

Best ResponseYou've already chosen the best response.0Wait for one second my mummy is calling me.. Have a look on that formula and try to memorize it and understand it as well..

Best ResponseYou've already chosen the best response.0Then there are as many formulas as there are hairs on my head And I don't like to be bald..

Best ResponseYou've already chosen the best response.0So let us hurry up I can explain you this thing..

Best ResponseYou've already chosen the best response.0See you are given with question like this: 2g of a NaCl is dissolved in 4 L of water.. Find the Molarity..

anonymous

Best ResponseYou've already chosen the best response.0Hurry up find the molecular mass of NaCl first..

anonymous

Best ResponseYou've already chosen the best response.0Because you have to find Number of Moles first..

anonymous

Best ResponseYou've already chosen the best response.0Now 2g you are given with.. Can you find number of moles now ??

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Yep solve it hurry up..

anonymous

Best ResponseYou've already chosen the best response.0Now can you find molarity by using its formula ??

anonymous

Best ResponseYou've already chosen the best response.0For that you need volume of solution too..

Best ResponseYou've already chosen the best response.0I don't know.. Ha ha ha..

anonymous

Best ResponseYou've already chosen the best response.0okay .. you leave then !

anonymous

Best ResponseYou've already chosen the best response.0For that you should know the density of water.. It will be given to you.. I think approximately density of water is 1.. So: \[Density = \frac{Mass}{Volume}\]

anonymous

Best ResponseYou've already chosen the best response.0Oh god what I am doing.. We have to find volume of NaCl not water..

anonymous

Best ResponseYou've already chosen the best response.0you better leave water ..

anonymous

Best ResponseYou've already chosen the best response.0Yeah but I will explain you after coming for sure.. May be till then others may help you.. Or I think I have written the question wrong...

anonymous

Best ResponseYou've already chosen the best response.0But the main concept is you got how to find number of moles of solute when it is not given.. Right ??

anonymous

Best ResponseYou've already chosen the best response.0It did increase some knowledge of yours. Okay now I have to leave.. There is work for me from my neighborers.. So I have to go now..
