Question

A sealed vessel contains 0. 200 mol of oxygen gas, 0. 100 mol of nitrogen gas, and 0. 200 mol of argon gas. The total pressure of the gas mixture is 5. 00 atm. The partial pressure of the argon is responses 0. 200 atm 0. 200 atm 0. 500 atm 0. 500 atm 1. 00 atm 1. 00 atm 2. 00 atm 2. 00 atm 5. 00 atm.

Answer 1

Below

Step-by-step explanation:

Each exerts pressure proportional to its fraction of the total

total = .200 + .100 + .200 = .500 mol

argon is .200 of this

.200 / .500 * 5 atm = 2 atm
