Problem

A stone is suspended from a spring balance and then fully immersed in water contained in a measuring cylinder. The following observations are made: • Weight of stone in air: 2.5 N2.5\,\text{N} • Initial water level: 100 mL100\,\text{mL} • Final water level: 160 mL160\,\text{mL} Take g=10 m/s2g = 10\,\text{m/s}^2. (a) Calculate the mass of the stone. (b) Calculate its density in kg m−3\text{kg\,m}^{-3}. (c) State whether the stone will sink or float in water and give a reason.
