Answer 1

Explanation:

hope this is your solution

Answer 2

Answer: Average molar mass of gas is 51.6 g

Explanation:

Molar mass of oxygen gas = 32 g

Moles of oxygen gas in mixture = 2

Mass of oxygen gas in mixture = Moles of oxygen  × molar mass

Mass of oxygen gas in mixture =   2 × 32 g = 64 g

Molar mass of CO₂ gas = 44 g

Moles of CO₂ gas in mixture = 3

Mass of CO₂ gas in mixture = Moles of CO₂  × molar mass

Mass of CO₂ gas in mixture =   3 × 44 g = 132 g

Molar mass of  SO₂ gas = 64 g

Moles of SO₂ gas in mixture = 5

Mass of SO₂ gas in mixture = Moles of SO₂  × molar mass

Mass of SO₂ gas in mixture =   5 × 64 g = 320 g

Total mass of mixture =  64 + 132 + 320 g

Total mass of mixture =  516 g

Total moles in mixture = 2 + 3 + 5

Total moles in mixture =  10

Average molar mass of mixture = Total mass / Total moles

Average molar mass of mixture  $= \frac{516}{10}$ g

Average molar mass of mixture = 51.6 g
