Block A in Fig. P12.74 hangs by a cord from spring balance D and is submerged in a liquid C contained in beaker B. The mass of the beaker is 1.00 kg; the mass of the liquid is 1.80 kg. Balance D reads 3.50 kg, and balance E reads 7.50 kg. The volume of block A is 3.80 Ã— 10^€“3m³.

(a) What is the density of the liquid?

(b) What will each balance read if block A is pulled up out of the liquid?
