Chapter 8, Problem 31E

Interpretation Introduction

(a)

Interpretation:

The number of molecules in $\text{0}\text{.150}\text{g}$ of carbon monoxide is to be calculated.

Concept introduction:

One mole of every gas occupies the same volume at STP. This value is equal to $\text{22}\text{.4}\text{L}$ and is known as the molar volume of the gas. The number of particles present in $\text{1}\text{mol}$ of any gas is equal to $6.022\times {10}^{23}$ and this value is known as the Avogadro’s number.
