You wish to determine the density of two unknown, immiscible liquids, A and B, at room temperature.  To do this you must measure the mass of a known volume of each liquid.  For  liquid A,  you  decide  to  use  a  volumetric  pipet  to  dispense  exactly  5.00 mL into  a convenient container.  Before dispensing the volume of liquid A into the container, you obtain and record the container’s mass as 2.83 grams.  After adding the 5.00 mL of liquid A to the container you reweigh the liquid containing container and find the combination to have a mass of 7.71-grams. What is the density of liquid A in g/mL?
