Best ResponseYou've already chosen the best response.1See 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.1solvent is water and solute is that 2g substance .. correct ?

Best ResponseYou've already chosen the best response.1For finding molarity you need number of moles solute.. How will you find number of moles of solute because it is given in 2 grams.. ??

waterineyes

Best ResponseYou've already chosen the best response.1For that there is a formula you will use that..

Best ResponseYou've already chosen the best response.1ah .. that previous one ?

Best ResponseYou've already chosen the best response.1derived from molarity .. ?

Best ResponseYou've already chosen the best response.1\[Number \; Of \; Moles = \frac{Grams \; Present}{Molecular \; Mass \; Of \; that \; Substance}\]

Best ResponseYou've already chosen the best response.1No no that one.. This one I have written above now..

Best ResponseYou've already chosen the best response.1how many formulas are there in this chapter ?

Best ResponseYou've already chosen the best response.1Now 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.1Wait 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.1Then 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.1So let us hurry up I can explain you this thing..

Best ResponseYou've already chosen the best response.1See you are given with question like this: 2g of a NaCl is dissolved in 4 L of water.. Find the Molarity..

waterineyes

Best ResponseYou've already chosen the best response.1Hurry up find the molecular mass of NaCl first..

waterineyes

Best ResponseYou've already chosen the best response.1Because you have to find Number of Moles first..

waterineyes

Best ResponseYou've already chosen the best response.1Now 2g you are given with.. Can you find number of moles now ??

waterineyes
 3 years ago
Best ResponseYou've already chosen the best response.1Yep solve it hurry up..

waterineyes

Best ResponseYou've already chosen the best response.1Now can you find molarity by using its formula ??

waterineyes

Best ResponseYou've already chosen the best response.1For that you need volume of solution too..

Best ResponseYou've already chosen the best response.1I don't know.. Ha ha ha..

waterineyes

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

waterineyes

Best ResponseYou've already chosen the best response.1Oh god what I am doing.. We have to find volume of NaCl not water..

ashna

Best ResponseYou've already chosen the best response.1you better leave water ..

waterineyes

Best ResponseYou've already chosen the best response.1Yeah 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...

waterineyes

Best ResponseYou've already chosen the best response.1But the main concept is you got how to find number of moles of solute when it is not given.. Right ??

waterineyes

Best ResponseYou've already chosen the best response.1It 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..
