Question

what is the total pressure of a gas mixture containing partial pressures of 0.23 atm, 0.42 atm, and 0.89 atm?
a. 0.51 atm
b. 1.54 atm
c. 0.42 atm
d. 0.89 atm

Explanation:

Step1: Recall Dalton's law

The total pressure of a gas mixture is the sum of the partial pressures of its components.

Step2: Add the partial pressures

$P_{total}=0.23 + 0.42+ 0.89$
$P_{total}=1.54$ atm

Answer:

B. 1.54 atm
