Chapter 3, Problem 3.125P

Interpretation Introduction

Interpretation:

Mass percentage of $\text{C}$ in the mixture of $\text{CO}$ and ${\text{CO}}_2$ is to be calculated.

Concept introduction:

The number of moles is calculated by the formula as given below:

  $\text{Number of moles}=\frac{\text{given mass of sample}\left(\text{g}\right)}{\text{molar mass (g/mol)}}$        (1)

The formula to calculate mass is as follows:

  $\text{Mass of a given sample}\left(\text{g}\right)=\left(\text{molecular mass}\left(\text{g/mol}\right)\right)\left(\text{number of moles}\right)$        (2)

Mass percent is defined as the mass of a component divided by the total mass of the mixture multiplied by 100.

The formula to calculate mass % is as follows:

  $\text{Mass }\%=\left(\frac{\text{given mass}\left(\text{g}\right)}{\text{total mass of mixture}\left(\text{g}\right)}\right)\left(100\%\right)$        (3)
