Can this be solved without converting to slugs

A cylindrical tank is constructed of steel and is completely sealed (i.e. it is not vented to the atmosphere). The tank inner diameter is 10ft and height is 12ft. The tank contains 16,000lbm of liquid chloroform, and the pressure in the headspace above the liquid is 25 psia. Atmospheric pressure is 14.7 psia. Report all the calculations and results using American units. a) Calculate the weight of the chloroform: b) Calculate the height of the liquid chloroform in the tank c) Calculate the absolute pressure at the bottom of the tank d) Calculate the gauge pressure at the bottom of the tank
