Answer:
24 moles
Explanation:
Based on the reaction:
Sn + 2HF → SnF₂ + H₂
1 mole of Sn and 2 moles of HF produce 1 mole of both SnF₂ and H₂.
48g of H₂ -molar mass 2.0g/mol- are:
48g × (1mol / 2.0g) = 24 moles of H₂
As 1 mole of SnF₂ is produced with 1 mole of H₂ and moles of H₂ produced were 24moles, moles of SnF₂ are 24 moles, too.
