Solutions

Chapter 8, Problem 4ALQ
Interpretation Introduction

(a)

Interpretation:

Percentage of each element present in calcium phosphate should be calculated.

Concept Introduction:

Molecular mass is the sum of all the elements atomic weight, multiplied by number of each atoms present in that compound’s chemical formula.

1 mole = molecular mass of the substance

Formula units is the empirical formula for an ionic and covalent compound. It is the ratio of all the elements present in the compound.

Interpretation Introduction

(b)

Interpretation:

If mass of phosphorus is 50.0 g, mass, number of moles and formula units of calcium phosphate should be calculated.

Concept Introduction:

From number of moles and molar mass, mass can be calculated as follows:

m=n×M

Here, n is number of moles and M is molar mass.

In 1 mol of a substance, there are 6.023×1023 units of the substance.
