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 deH_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 deH_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
