Question

Calculate the molecular mass of the following:

a) CuSO4.5H2O

b) (NH4)2CO3

c) (NH2)2CO

d) Mg3N2

Given atomic mass of Cu = 63.5; H = 1; O = 16; C = 12; N = 14; Mg = 24; S = 32​

Answer 1

Answer:

1 ) Cuso4.5h20

(63.5)+(32)+(16)(4)+5(18)

63.5 + 32 + 64 + 90 = 249.5 amu

2) (NH4)2CO3

(14 + 4)(2) + 12 + (16)(3)

36 + 12 + 48 = 96 amu

3 ) (NH2)2 CO

(14 + 2 ) (2) + 12 + 16

36 + 12 + 16

64 amu

4 ) mg3 n2

24× 3 + 14 × 2

72 + 28

100 amu
