Arectangular block of solid carbon (graphite) floats at the interface of two immiscible liquids.
the bottom liquid is a relatively heavy lubricating oil, and the top liquid is water. of the total block volume, 59.2% is immersed in the oil and the balance is in the water.
in a separate experiment, an empty flask is weighed, 35.3 cm3 of the lubricating oil is poured into the flask, and the flask is reweighed.
if the scale reading was 124.8 g in the first weighing, what would it be in the second weighing? (suggestion: recall archimedes' principle and do a force balance on the block.)
you may take the density of graphite as 2.16 g/cm3.
