Ideal Gas Law: PV = nRTConstant R = 0.8206 L · atm/mol14.7 psi = 1 atmIdeal Gas Law:

Explanation:

Step 1: Define variables

n = 0.275 moles

T = 75 K

P = 17.5 psi

V = unknown

Step 2: Solve for V

Convert psi to atm:          17.5 psi = 1.19048 atmSubstitute:                        1.19048 atm · V = (0.275 mol)(0.08206)(75 K)Multiply:                            1.19048V = 1.69249Isolate V:                           V = 1.42169 L
