a flask contains oxygen, carbon dioxide, and nitrogen gases. the partial pressures of each are 11.4 atm, 5.6…

Explanation:

Step1: Recall Dalton's law

The total pressure $P_{total}$ of a gas - mixture is the sum of the partial pressures of its components. $P_{total}=P_1 + P_2+P_3$

Step2: Identify partial pressures

Let $P_1 = 11.4$ atm (oxygen), $P_2 = 5.6$ atm (carbon - dioxide), and $P_3 = 8.7$ atm (nitrogen).

Step3: Calculate total pressure

$P_{total}=11.4 + 5.6+8.7$ $P_{total}=25.7$ atm

Answer:

25.7 atm
