Suppose two gases in a container have a total pressure of 1.30 atm. What is the pressure of gas B if the partial pressure of gas A is 0.85 atm?

P (B) = 0.45 atm

Explanation:

Given dа ta:

Total pressure = 1.30 atm

Partial pressure of A = 0.85 atm

Pressure of B = ?

Solution:

Total pressure = P (A) + P (B)

P (B) = Total pressure - P (A)

P (B) = 1.30 atm - 0.85 atm

P (B) = 0.45 atm
