Dear Student,

Please ask only one question per thread.
Here, I am answering Q. 33

M.W. of H2O = 18.
So, 18g of H2O has one mole i.e. 6.022 x 1023 molecules
So, 9g of H2O has 3.011 x 1023 molecules

M.W. OF NH3 = 17
So, 17g of NH3 has one mole i.e. 6.022 x 1023molecules 

Hope this information will clear your doubts about topic.
If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible.

18g of h20 has 6.022 x 1023 molecules
therefore 18 by 2 that is 9g of h2o has 3.011 x 1023 molecules

similarly 17g of nh3 has 6.022 x 1023molecules that is 1 mole
hope it helps for the moment
