Answer 2

The molecular mass of a substance is the sum of the atomic masses of all the atoms in a single molecule of that substance. Like atomic mass, molecular mass is also expressed in the unit Dalton (u).

Question:

Calculate the molecular mass of CA(OH)2

= (Atomic mass of Ca)× 1+ (Atomic mass of O+ Atomic mass of H)× 2

= (40×1)+ (16×1)× 2

= 40+ (17×2)

= 40+ 34= 74

Molecular mass of Ca(OH)2= 74.
