292.4 g

Explanation:

2Al + 3H₂SO₄ → 3H₂ + Al₂(SO₄)₃

First we convert 53.7 g of Al into moles, using its molar mass:

53.7 g ÷ 27 g/mol = 1.99 mol Al

Then we convert Al moles into H₂SO₄ moles, using the stoichiometric coefficients:

1.99 mol Al * $\frac{3molH_2SO_4}{2molAl}$ = 2.98 mol H₂SO₄

Finally we convert 2.98 moles of sulfuric acid into grams, using its molar mass:

2.98 mol H₂SO₄ * 98 g/mol = 292.4 g
