Homework Help: chemistry

Posted by kellie on Monday, September 20, 2010 at 10:38am.

a. How many atoms of hydrogen are in 25.0 g of ammonia (NH3)? Use the format 6.02E+23 for 6.02 x 10^23


b. How many atoms of nitrogen are in the same amount of ammonia

I know to find the number of atoms in a gram of a sample you must multiply by 6.02*10^23.

So i multiplied 25*6.02*10^23
ammonias Molecular mass = 17.03
so do i divide 25.0/17.03=1.468 mol NH3

what next
