How many moles of SnF₂ will be produced along with 48 grams of H₂? *

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.

1. they vary with a higher number because boiling is way hotter than melting
