Expert Solution
Step 1

Given that number of moles of NH3 = 3.54 mol

Molar mass of NH3 = 17.03 g/mol ( from standard data)

[It can also be calculated roughly using the molar mass of each element atom as: atomic mass for N = 14 g/mol, for H = 1 g/mol

Hence, for NH3 = (1×N) + (3×H)= (1 × 14) + (3×1) = 17 g/mol approximately]

Now, the mass can be obtained from moles and molar mass using following equation:

Mass = moles × molar mass
