Question

calculate the molecular mass (1) Cuso4 (step by step explanation).​

Answer 1

Explanation:

atomic mass of Cu = 63.5u

atomic mass of S = 32u

atomic mass of O = 16u

molecular mass = 63.5+32+4×16

= 159.5u

Answer 2

Explanation:

Molecular mass of a compound is the sum of atomic masses of each element present in the molecule. 

Molecular mass = atomic mass of Cu + atomic mass of S + (4 × atomic mass of O)

= 63.5 + 32 + 4 × 16 = 95.5 + 64 =159.5 gm/mole
