Question
What is the mass of a sample of ammonia that contains 0.750 moles of hydrogen atoms?
The answer is 4.26g, but I do not know how to set up the equation.

Ammonia is NH3.
0.750 mols H atoms x (1 mol NH3/3 mol H atoms) = 0.250 mol NH3
Then g NH3 = mols NH3 x molar mass NH3 = 0.250 x 17 = ?
0.750 mols H atoms x (1 mol NH3/3 mol H atoms) = 0.250 mol NH3
Then g NH3 = mols NH3 x molar mass NH3 = 0.250 x 17 = ?
