Question

initial volume of hydrogen is 80cm3 at 150mm Hg and 104°F and
oxygen whose volume is 90cm3 at 250 mm hg is added to it Find total
pressure of mixture

The given condition is maintained at the same temperatureSo P1V1 + P2V2 =P3V3  150 × 80 + 250 × 90 = P3 × (90+80)P3 = 150 × 80 + 250 × 90(90+80) =83
82 mm

initial volume of hydrogen is 80cm3 at 150mm Hg and 104°F and oxygen whose volume is 90cm3 at 250 mm hg is added to it. Find total pressure of mixture
