my teacher wasn't in school and this assignment is due @ 7am!!!!!

The density of gasoline is 730 kg per cubic meter. One gallon of gasoline occupies .0038 cubic meters. Gasoline's volume expansion coefficient is .00096` C (^-1).

How many extra kilograms of gasoline are obtained when 9 gallons of gasoline are bought at 0` C rather than at 18` C (temp. at the filling station) ?

answer should be in kg???
