Answer:
The answer to your question is 0.98 g of H₂
Explanation:
Data
mass of H₂ = ?
mass of Zn = 31.8 g
Balanced chemical reaction
Zn + H₂SO₄ ⇒ ZnSO₄ + H₂
Process
1.- Calculate the molar mass or atomic mass of Zinc and hydrogen
The Atomic mass of zinc = 65 g
The Molar mass of H₂ = 2 g
2.- Use proportions and cross multiplication to find the mass of H₂ formed.
65 g of Zn ----------------- 2 g of H₂
31.8 g of Zn -------------- x
x = (31.8 x 2) / 65
x = 63.6/65
-Result
x = 0.98 g of H₂
