Chapter SH, Problem 15.5APP

To determine

To calculate: Mass of oxygen that reacted with carbon.

Answer to Problem 15.5APP

Mass of oxygen is $\underset{\_}{\text{320 g}}$ .

Explanation of Solution

Given:

The following equation:

  $\text{C}+{\text{O}}_2\to {\text{CO}}_{\text{2}}$

Mass of carbon = $\text{120 g}$

Mass of carbon dioxide = $\text{440 g}$

Calculation:

According to law of conservation of mass,

Total mass of reactants = Total mass of products

Therefore, total mass of reactants = $\text{800 g}$

Mass of oxygen is calculated as:

  $\begin{array}{l}\text{ Total mass}-\text{mass of carbon}\\ =440\text{ g}-120\text{}\text{ g}\\ =320\text{ g}\end{array}$

Conclusion:

Mass of oxygen is $\underset{\_}{\text{320 g}}$ .
