## Calculate the molar mass of the following substances.a. b. Ca3(PO4)2c. Na2HPO4

(a)

Interpretation Introduction

Concept introduction: The atomic mass is defined as the sum of number of protons and number of neutrons.

The molar mass of any compound can be calculated by adding of atomic weight of individual atoms present in it. Also one mole of any compound is same as atomic weights.

To determine: The molar mass of P4O6 .

### Explanation of Solution

The atomic weight of phosphorous (P) is 30.973g/mol .

The atomic weight of oxygen (O) is 15.999g/mol .

In a compound P4O6 , four phosphorous and six oxygen atoms are present. Hence, atomic weight of these atoms is,

4P=30.973g/mol×4=123.892g/mol6O=15

(b)

Interpretation Introduction

Concept introduction: The atomic mass is defined as the sum of number of protons and number of neutrons.
