The density of gasoline is ρ = 0.730×103 kg/m^3 at 0ºC. Its average coefficient of volume expansion is α(sub v) = 9.60×10^-4 (ºC)-1. If 1.00 gallons of gasoline occupies 0.00380 m^3, how many extra kilograms of gasoline would you get if you bought 10.0 gallons of gasoline at 0ºC rather than at 20.0ºC from a gasoline pump that is not temperature compensated?

The definition of thermal volume expansion coefficient:
$$\Delta V/V_0 = \alpha_v \Delta T$$.
