1-butanol (shown below) burns in the presence of oxygen to give off carbon dioxide and water by the following reaction:
C4H9OH + 6 O2 ==> 4 CO2 + 5 H2O
If 40.88 mL of 1-butanol burns completely, how many grams of 1-butanol have burned? grams

=33.1

bu then
Now, How many moles of 1-butanol does this number of grams represent?

molar mass/grams? my answer says it's wrong though... which is 8.03

• chemistry -

mols = grams/molar mass
