Write the formula of the Ammonium Oxalate compounds and calculate the molecular mass.

Answer»

Ammonium Oxalate-(NH4)2C2OMolecular mass = (2 x (1 x atomic mass of N + 4 x atomic mass of H)) + (2 x atomic mass of C) + (4 × atomic mass of O)
= 2(14 + 4) + (2 × 12) + (4 × 16)
= 36 + 24 + 64 = 124 g/mol
