Question

An excess mass of Al reacts with 0.375 mol H₂SO₄ . How much volume of hydrogen gas release at room temperature. [ Molar volume at room temperature = 24 L/mol ]

Answer 1

An excess mass of Al reacts with 0.375 mol H₂SO₄ . How much volume of hydrogen gas release at room temperature. [ Molar volume at room temperature = 24 L/mol ]

Reation involved b/w AT and H2SO4

2 Mole AI , 3 Mole H2SO4

Hence , 3 Mole of H2SO4 gives 3 Mole of Hydrogen gas .

So , 0.375 Mole of H2So4 gives 0.3 moles of hydrogen gas .

Moles of hydrogen gas release = 0.375 .

Volume of hydrogen gas release = 3 l
