grams acetone = volume x density = ?
1790 x (grams acetone/molar mass acetone) = ?
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.

so 1790 x (183/58.08) ?
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.
You must use the density to convert 183 mL to grams.
