✔ 最佳答案
The total pressure is equal to the sum of the partial pressures of the individual gases. So:2.1 atm = 1.2 atm + 0.6 atm + PH2
PH2 = 0.3 atm

According to Dalton's law of partial pressures :
P(Total) = P(H₂) + P(O₂) + P(N₂)
Partial pressure exerted by the hydrogen gas, P(H₂)
= P(Total) - P(O₂) - P(N₂)
= (2.1 - 1.2 - 0.6) atm
= 0.3 atm
P(Total) = P(H₂) + P(O₂) + P(N₂)
Partial pressure exerted by the hydrogen gas, P(H₂)
= P(Total) - P(O₂) - P(N₂)
= (2.1 - 1.2 - 0.6) atm
= 0.3 atm
