Moles of O₂ = 8/1 (Given). Calculate the weight of O₂.

1. M.W. of O₂
2. weight of H₂
3. weight of O₂
4. 8/1

Correct answer: weight of O₂

Solution

The weight of O₂ can be calculated using the formula: weight = moles × molar mass. Given moles of O₂ = 8, and molar mass of O₂ = 32 g/mol, the weight is 8 × 32 = 256 g.
