A flask contains 36% nitrogen ,39% oxygen and 26% hydrogen. If the total pressure of the mixture of gases is 500 mm, the partial pressure of oxygen is
Options
(a) 120 mm
(b) 145 mm
(c) 195 mm
(d) 210 mm
Correct Answer:
195 mm
Explanation:
According to Dalton’s law of partial pressures
P(total) = Pɴ₂ + Po₂ + Pʜ₂
As the % age of oxygen is 39% and total pressure is 500 mm.
.·. Partial pressure os oxygen is 39% of 500 = 195 mm
