Answer:
134.4 L
Explanation:
1. Find number of moles for Al
Number of moles
= mass ÷ molar mass
= 108 g ÷ 27
= 4 moles
2. Do comparison
From the equation, 2 moles of Al yields 3 moles of H2 gas.
Therefore, 4 moles of Al should yield 6 moles of H2 gas.
Calculation:
4 moles ÷ 2 moles x 3 moles = 6 moles of H2 gas
3. Convert to liters
Liters of H2 gas
= Number of moles x molar volume
= 6 moles x 22.4 L
= 134.4 L
