how di i use PV=nRT for: How many moles of oxygen gas (O2) are in 448L at STP (273K and 1 atm of pressure)?

need help!

  • chemistry -

    PV = nRT
    P = 1 atmosphere
    V = 448 L (that sounds high, perhaps it is 4.48 L or sometime similar.)
    n = what you solve for.
    R = universal gas constant = 0.08206 L*atm/mol*K
    T = 273 K.
