Dichloromethane has a specific gravity of 1.33: a) What is the mass (kg) of 75 liters? b) What is the volumetric flow rate (L/min) of the dichloromethane entering a storage tank if the mass flow rate is 960 kg/min. c) Chloroform (specific gravity = 1.483) is mixed with this dichloromethane during one of the processes at the plant. The two liquids are blended until a specific gravity of 1.445. Determine the mole percentage of the two components in the blend
