Answer:
27g of Al
Explanation:
2AI + 6HCI —> 2AIC3 + 3H2
molar mass of Al = 27 g/mol
Mass conc of Al from the balanced equation = 2 x 27 = 54g
Molar Mass of H2 = 2x1 = 2g/mol
Mass conc of H2 from the balanced equation = 3 x 2 = 6g
From the equation,
54g of Al produced 6g of H2.
Therefore, Xg of Al will produce 3g of H2 i.e
Xg of Al = (54x3)/6 = 27g
