Question

Ethanol burns according to the following equation. If 15.0 mol of $\mathrm{C_2H_5OH}$ burns this way, how many moles of oxygen are needed?

Answer:

According to the reaction equation:

$$\begin{array}{l} 1 \text{ mol of } \mathrm{C_2H_5OH} \text{ needs } 3 \text{ mol of } \mathrm{O_2} \\ 15.0 \text{ mol of } \mathrm{C_2H_5OH} - x \text{ mol of } \mathrm{O_2} \\ x = \frac{15.0 \cdot 3}{1} = 45.0 \text{ mol} \end{array}$$

Answer: 45.0 mol of oxygen
