Question

There are 3 gases in a container, methane has a partial pressure of 1.23 atm, ethane's partial pressure is 1.48 atm and an unknown pressure of propane. The pressure in the container was measure to be 4.43 atm. What is the partial pressure of propane?

A) 1.72
B) 1.35
C) 1.69
D) 1.53

Answer 1

A) 1.72 atm

Step-by-step explanation:

Dalton's Law of Partial Pressures

`P_(t) = P_(1) + P_(2) + P_(3) ....`

4.43 atm = 1.23 atm + 1.48 atm + x

x = 4.43 atm - (1.23 atm + 1.48 atm)

x = 1.72 atm
