PROBLEM 63P

A cylinder contains 11.8 L of air at a total pressure of 43.2 psi and a temperature of 25 °C. How many moles of gas does the cylinder contain?

Solution 63P:

Here, we need to calculate the amount of gas in the cylinder.

Step1: We now,

From the ideal gas equation ------(1)

Step 2:

Given that

P = 43.2 psi

Conversion from psi to atm

1 atm = 14.69psi

P = 43.2 psi x = 2.393 atm

T = 25 + 273 = 298 K

Thus,

V = 11.8 L

R= 0.08206 L atm K-1mol-1

n =?
