Answer: 27g
Explanation:
2AL + 6HCL —> 2ALCL3 + 3H2
Molar Mass of Al = 27g/mol
Mass conc. of Al from the equation = 2x27 = 54g
Molar Mass of H2 = 2x1 = 2g/mol
Mass conc. of H2 from the equation = 3 x 2 = 6g
From the equation,
54g of Al reacted to produced 6g of H2.
Therefore, Xg of Al will react to 3g of H2 i.e
Xg of Al = (54x3)/6 = 27g
