Calculate the molecular mass of the following:
Na2SO4.10H2O
Given atomic masses of Na = 23, H = 1, O = 16, C = 12, N = 14, Mg = 24, S = 32
Calculate the molecular mass of the following compound:
Na2SO4.10H2O

उत्तर
Atomic Masses: Na = 23, S = 32, O = 16, H = 1
(2 × 23) + 32 + (4 × 16) + 10 × [(2 × 1) + 16]
= 46 + 32 + 64 + 180
= 322 u
