1. Convertir gramos de H_2 a moles:
\frac{10 \text{g } H_2}{2 \text{ g/mol}} = 5 \text{ mol } H_2
2. Usar la estequiometría de la reacción para encontrar moles de H_2O producidos:
5 \text{ mol } H_2 \times \frac{2 \text{ mol } H_2O}{2 \text{ mol } H_2} = 5 \text{ mol } H_2O
3. Convertir moles de H_2O a gramos:
5 \text{ mol } H_2O \times 18 \text{ g/mol } = 90 \text{ g } H_2O
4. Resultado final:
90 \text{ g } H_2O
