a 20.0 liter flask contains a mixture of argon at 0.72 atmosphere and oxygen at 1.65 atmosphere. what is the total pressure in the flask

Total pressure in flask is 2.37 atm.

Explanation:

According to the Dalton's law of partial pressure, the total pressure of the flask would be the sum of partial pressure of the gases present in mixture.

P (total) = P1 + P2+P3 + ... Pn

n = number of gases present

Given dа ta:

Pressure of argon gas = 0.72 atm

Pressure of oxygen gas = 1.65 atm

Total pressure in flask = ?

Solution:

P (total) = P (argon) + P (oxygen)

P (total) = 0.72 + 1.65

P (total) = 2.37 atm
