    Density of the air
    Help required to solve my chemistry homework problem

    If Air contains 80% of nitrogen and 20% oxygen by volume, approximately. Then what could be the density of air at 0 degree centigrade and 1 atmosphere?

    Thanks

    What is density at STP? What is formula for determining density with constant P but varying T? Look up "Ideal Gas Law" which is in your book.
