Consider the following thermochemical equation for the combustion of acetone (C3H6O), the main ingredient in nail polish remover:
C3C6O + 4 O2 --> 3 CO2 + 3H2O

DELTA Hrxm= -1790kJ

If a bottle of nail polish remover contains 183 mL of acetone, how much heat would be released by its complete combustion? The density of acetone is 0.788 g/mL.

  • Chemistry - ,

    grams acetone = volume x density = ?

    1790 x (grams acetone/molar mass acetone) = ?

  • Chemistry - ,

    so 1790 x (183/58.08) ?

  • Chemistry - ,

    No. You don't have 183 g acetone do you? That's 183 mL acetone, not grams.
    You must use the density to convert 183 mL to grams.
