The density of liquid oxygen at its boiling point is 1.14 \rm{kg/L} , and its heat of vaporization is 213 \rm{kJ/kg} .

How much energy in joules would be absorbed by 4.0 L of liquid oxygen as it vaporized?

Calculate the number of kg in 4.0 liters of liquid, using the density. Then multipy that by the heat of vaporization.
density of a ring mass 38.6g and volume 2cm
