Chapter 1, Problem 36P

Interpretation Introduction

Interpretation: The number of atoms of silicon needs to be determined.

Concept Introduction: From number of moles and molar mass of a substance, the mass can be calculated using the following relation:

  $m=n\times M$

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

Also, in 1 mol of any substance, there are $6.023\times {10}^{23}$ units of that substance.

The density is defined as mass per unit volume. It is mathematically represented as follows:

  $d=\frac{m}{V}$

Here, m is mass and V is volume.
