A Rectangular Block Of Solid Carbon Graphite Floats At The

A rectangular 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, 54.2% 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 124.8g in the first weighing, what would it be in the second weighing? (Suggestion: Recall Archimedes’ principle, and does a force balance on the block.
