    To solve this problem, the temperature must be in ˚K.

    T = 34.80 + 273 = 307.8˚K

    Let’s use the following equation

    P * V = n * R * T

    R = 22.4 ÷ 173

    1.77 * V = 90.5 * (22.4 ÷ 273) * 307.8

    V * 483.21 = 623,772.16

    V = 623,772.16 ÷ 483.21

    The volume is approximately 1,300 liters.

    Ideal gas equation ....

    "Plug and chug." Solve the ideal gas equation for "V", then plug in the numbers, turn the crank, and out pops the answer.

    PV = nRT

    V = nRT / P

    V = 90.5 mol x 0.08206 Latm/molK x (273.15 + 34.80)K / 1.77 atm

    V = 1290L

    The answer can only be expressed to three significant digits.

    PV = nRT

    V = (90.5 X 0.0821 X 307.8) / 1.77 <<< use a calculator
