Block A 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 and the mass of liquid is 1.80 kg. Balance D reads 3.50 kg and balance Balance E( supporting beaker B) reads 7.50 kg. The volume of block A is 3.80 * 10^-3 m^3. a) What is the density of the liquid? b) What will each balance read when Block A is pulled out of liquid? Do I need to know what the liquid is in order to solve this? I know that p(density) = mass/volume. So in this case is it just mass of liquid/volume of liquid?
