According to Dalton's Law of Partial pressures, the sum of the partial pressures of the individuals gas molecules that occupy a specific volume allows us to find the total pressure or find one of the partial pressures if the total pressure is known.

Partial pressure O2 = 632 - 124.3 - 461.9 = 45.8 mm Hg.

Molar mass of butane:-

  • 4(12)+10=58u

Moles of Butane:-

  • 100/58=1.7mol

#16

  • 2mols of Butane produce 8mol CO_2
  • 1mol of butane produces 4mol CO_2

Moles of CO_2

  • 4(1.7)=6.8mol

Mass of CO_2:-

  • 44(6.8)=299.2g

#17

  • 2mols of butane need 13mol O_2
  • 1mol of butane needs 6.5mol O_2

Moles of O_2

  • 6.5(1.7)=11.05mol

Mass of O_2

  • 11.05(32)=353.6g
