Question

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?

Answer 1

Answer: 1.20 atm

Step-by-step explanation:

partial pressure of argon = 3.75 atm - 0.75 atm - 1.80 atm

partial pressure of argon = 1.20 atm

Therefore, the partial pressure of argon in the mixture is 1.20 atm

Answer 2

To find the partial pressure of argon, we need to use the fact that the sum of the partial pressures of all the gases in the mixture is equal to the total pressure:

partial pressure of argon + partial pressure of oxygen + partial pressure of nitrogen = total pressure

Let's rearrange this equation to solve for the partial pressure of argon:

partial pressure of argon = total pressure - partial pressure of oxygen - partial pressure of nitrogen

Substituting the given values, we get:

partial pressure of argon = 3.75 atm - 0.75 atm - 1.80 atm

partial pressure of argon = 1.20 atm

Therefore, the partial pressure of argon in the mixture is 1.20 atm.
