a sealed vessel containing argon, oxygen, and nitrogen has a total pressure of 3.75 atm and partial pressures of 0.75 atm for oxygen and 1.80 atm for nitrogen. what is the partial pressure of argon in atm? p of ar (atm)

a sealed vessel containing argon, oxygen, and nitrogen has a total pressure of 3.75 atm and partial pressures of 0.75 atm for oxygen and 1.80 atm for nitrogen. what is the partial pressure of argon in atm? p of ar (atm)

Answer

Explanation:

Step1: Recall Dalton's law

According to Dalton's law of partial - pressures, the total pressure ($P_{total}$) of a gas mixture is the sum of the partial pressures of its components. So, $P_{total}=P_{O_2}+P_{N_2}+P_{Ar}$.

Step2: Rearrange the formula to solve for $P_{Ar}$

We can rewrite the formula as $P_{Ar}=P_{total}-P_{O_2}-P_{N_2}$.

Step3: Substitute the given values

Given $P_{total} = 3.75$ atm, $P_{O_2}=0.75$ atm, and $P_{N_2}=1.80$ atm. Then $P_{Ar}=3.75 - 0.75-1.80$.

Step4: Calculate the result

$P_{Ar}=1.20$ atm.

Answer:

1.20 atm
