Answer

Explanation:

Step1: Identify given values

Let $P_T = 1.25$ atm, $P_1=0.68$ atm, $P_2 = 0.35$ atm.

Step2: Apply the partial - pressure formula

We know $P_T=P_1 + P_2+P_3$. Rearranging for $P_3$ gives $P_3=P_T-(P_1 + P_2)$. Substitute the values: $P_3=1.25-(0.68 + 0.35)$. First, calculate the sum inside the parentheses: $0.68+0.35 = 1.03$ atm. Then, $P_3=1.25 - 1.03$. $P_3 = 0.22$ atm.

Answer:

A. 0.22 atm
