Question

4. How many moles of H, would be

produced from 47 grams of H2SO4?
2A1 +3H,504 → Al2(SO4)3 +3H2

Answer 1

0.48 moles of H₂ are produced.

Step-by-step 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.
