Given the following equation: N2(g) + 3H2(g) = 2NH3(g).
Determine to one decimal place the molar mass of each term, and WRITE EACH ONE AS A CONVERSION from moles to grams.

I will do one:

NH3=14.0+2*1.0=16.0

1mole=16.0 grams, or Unitconversionfactor= 16grams/mole

N on the periodic table is 14.0067
N2 = 2*14.0067 = 28.0134 which rounds to 28.0 to one decimal place.
1 mole N2 x (28.0 g/mol) = 28.0 grams.

The others are done the same way.
