Solution

part A: molar mass of N2 = 2*(14.0067) = 28.01 g/mol

part B:

molar mass of KH₂PO₄ = 1(39.0983) + 2(1.0079) + 1(30.9738) + 4(16.0)

molar mass of KH₂PO₄ = 39.0983 + 2.016 + 30.9738 + 64.0 = 136.09 g/mol

Therefore, molar mass of  KH₂PO₄ = 136.09 g/mol

part C:

molar mass of Fe(ClO₄)₃ = 1(55.845) + 3(35.453) + 12(16.0)

molar mass of Fe(ClO₄)₃ = 55.845 + 106.36 + 192 = 354.21 g/mol
