?Al + ?H2SO4 → ?Al2(SO4)3 +3H2
AfilCa [17]

The answer is: 27 grams of aluminium.

Balanced chemical reaction: 2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂.

n(H₂) = 1.5 mol; amount of hydrogen.

Form chemical reaction: n(Al) : n(H₂) = 2 : 3.

n(Al) = 2 · 1.5 mol ÷ 3.

n(Al) = 1.0 mol; amount of aluminium.

m(Al) = n(Al) · M(Al).

m(Al) = 1 mol · 27 g/mol.

m(Al) = 27 g; mass of aluminium.

What is the molarity of a 9.13 L soda that contains 13.83 of sugar?
choli [55]

Answer:

1.52 M

Explanation:

Molarity of a solution is calculated as follows:

Molarity = number of moles (n) ÷ volume (V)

Based on the information given in this question,

Volume of soda (V) = 9.13 L

number of moles = 13.83 mol

Molarity = 13.83 ÷ 9.13

Molarity = 1.52 M
