Homework Help: Volume gas occupies

  1. Nov 30, 2006 #1
    1. The problem statement, all variables and given/known data
    A mass of 0.582 kg of molecular oxygen is contained in a cylinder at a pressure of 1.0 × 10^5 Pa and a temperature of 1°C. What volume does the gas occupy?


    2. Relevant equations

    PV = nRT

    3. The attempt at a solution

    15.9994 * 2 = 31.9988 amu
    532g / 31.9988 amu = 16.62604 mol

    K=1 + 273 = 274

    (16.62604 x 8.3145 x 274)/100,000
    = .3788m^3

    This is wrong according to my book...Any ideas why?

    The problem statement lists 0.582kg, and you use 532g in your calculation.

    According to google.com: 0.582 kilograms = 582 grams?

    Yeah, so why'd you use 532 in your calculation? A typo?
