    PV=nRT

    (66.7kPa)(.55L) = n(8.314)(284.15K)
    n= 0.0155mol

    use the ideal gas formula. PV=nRT.
    P = 66.7
    V = .550 L
    n = unknown
    R = 8.31
    T = 284 (273 + 11)

    Plug the numbers in and get n = .0155 moles

    Use the ideal gas law (R= 8.31 KPa L/mol K) to determine how many moles of a gas...

    ...occupy a 550-mL canister at ? 11 degrees celcius and 66.7 kPa pressure.

    A. 0.00155 mol
    B. 0.0155 mol
    C. 0.401 mol
    D. 15.5 mol

    please help.
