Molecular & Formula Mass Worksheet - Key

Molecular & Formula Mass Worksheet - Key. Calculate the molecular mass of each of the following molecular compounds. 4(H) + 2(C) + 2(O) = 4(1.0) + 2(12.0) + 2(16.0) = 4.0 + 24.0 + 32.0 = 60.0 amu. 5(C) + 10(H) + 2(N) + 3(O) = 5(12.0) + 10(1.0) + 2(14.0) + 3(16.0)
