Question

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

Answer 1

Answer:

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 data:

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
