Answer:
0.48 moles of H₂ are produced.
Explanation:
Given data:
Number of moles of H₂ produced = ?
Mass of H₂SO₄ = 47 g
Solution:
Chemical equation:
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
Number of moles of H₂SO₄ :
Number of moles = mass/molar mass
Number of moles = 47 g/ 98 g/mol
Number of moles = 0.48 mol
Now we will compare the moles of H₂SO₄ and H₂
H₂SO₄ : H₂
3 : 3
0.48 : 0.48
Thus, 0.48 moles of H₂ are produced.
