Answer

Explanation:

Step1: Identify given values

Let $P_T = 1.25$ atm, $P_1=0.68$ atm, $P_2 = 0.35$ atm, and we want to find $P_3$ (pressure of helium). The formula is $P_T=P_1 + P_2+P_3$.

Step2: Rearrange the formula

We can rewrite the formula as $P_3=P_T-(P_1 + P_2)$.

Step3: Substitute values

$P_3=1.25-(0.68 + 0.35)$. First, calculate $0.68+0.35 = 1.03$ atm. Then $P_3=1.25 - 1.03$.

Step4: Calculate the result

$P_3 = 0.22$ atm.

Answer:

0.22 atm
