Question

The density of gasoline is 0.72 grams per cubic centimeter. What is the mass in units of kilograms of a 5-gallon container filled completely with gasoline? Ignore the mass of the container.
Mass = 0.00072kg/cm^3 * 37854cm^3/gal * 5gal. = 136.3 kg.
5gal / 0.264gal * 1000mL / 1mL=18939.39cm^3

.72g/cm^3 * 18939.39cm^3= .72g * 18939.39

18939.39 * 0.72g = 13636.36g/1000g = 13.63kg
