How many moles of nitrogen are required to produce 13.5 grams of NH3

0.794 moles

Explanation:

Gviven that:

TO find the number of moles of nitrogen (N) using the formula:

number of moles  = mass /molar mass

where;

the molar mass for NH3 = 14 +( 1 × 3) = 17 g/mol

∴

number of moles of (N) = mass of N/molar mass

= 13.5 g/17 g/mol

number of moles of (N) = 0.794 moles
