Homework Help: Cylindrical Canister Mole Problem

  1. Sep 22, 2008 #1
    1. The problem statement, all variables and given/known data

    An empty cylindrical canister 1.50 m long and 94.0 cm in diameter is to be filled with pure oxygen at 30.0 C to store in a space station. To hold as much gas as possible, the absolute pressure of the oxygen will be 21.5 atm . The molar mass of oxygen is 32.0 g/mol .

    2. Relevant equations

    How many moles of oxygen does this canister hold?
    For someone lifting this canister, by how many kilograms does this gas increase the mass to be lifted?

    3. The attempt at a solution
