Consider the equation:
N2 + 3 H2 =>2 NH3.

How many moles of NH3 will be made from 9.2 x 1023 molecules of H2? Give your answer to one decimal place.

Answer
9.2*10^23 molecule H2 * (1 mol H2 /6.022*10^23 molecule H2) * ( 2 mol NH3 / 3 mol H2 )
1.108 mol NH3
1.1 mol NH3

Consider the equation:
N2 + 3 H2 =>2 NH3.

How many moles of NH3 will be made from 4.2 x 1025 molecules of N2? Give your answer to one decimal place.

Answer
N2 + 3 H2 ===================>2 NH3.
The molar ratio is 1 N2 : 2 NH3 and 1 mol = 6.022*10^23 molecule

4.2*10^25 molecule N2 * (1 mol H2 /6.022*10^23 molecule N2) * ( 2 mol NH3 / 1 mol N2 )
139.48 mol NH3 = 139.5 mol NH3
