Question

How many moles of oxygen are needed to produce 25.4 moles of carbon dioxide?

Answer 1

How many moles of oxygen are needed to produce 25.4 moles of carbon dioxide?

Data:

$$C + \begin{array}{c} x \text{ moles} \\ O_2 \\ 1 \text{ mole} \end{array} = \begin{array}{c} 25,4 \text{ moles} \\ CO_2 \\ 1 \text{ mole} \end{array}$$

Solving the proportion:

$$x = \frac{1 \text{ mole} \times 25,4 \text{ moles}}{1 \text{ mole}}$$ $$x = 25,4 \text{ moles}$$

The solution: 25,4 moles of oxygen are necessary for producing 25.4 moles of carbon dioxide.
