Answer
P = 1.63 atm or 23.9 psi
Work Step by Step
An 8.50-L tire contains 0.552 mol of gas at a temperature of 305 K. What is the pressure
V = 8.5, n = 0.552, T = 305, P = ?
using PV = nRT (where R = 0.08206)
P = 0.552 x 0.08206 x 305 / 8.50
= 1.63 atm
1atm = 14.7 psi
1.63 atm = 14.7 x 1.63 psi
= 23.9 psi
