One gallon of gasoline (3785 ml) has a mass of 2640 g. what is the density of gasoline

d = 0.6975 g/cm³

Explanation:

d = m/V       d = density      m = mass      V = volume

1 mL = 1 cubic centimeter

d = 2640 g / 3785 cm³

d = 0.6974900925 g/cm³

four significant digits in problem, so four significant digits in answer

fe 55.85 g/mol and h2o 18.02 g/mol.
