A solid of mass 400g in air and when partly is immersed in a certain liquid it has a mass 320g. Given that the relative density is 0.8. Calculate the volume of the solid immersed in the liquid.

Volume of solid immersed = (400-320) / (0.8 g/mL) = 40/0.8 = 50 mL Explanation: The volume of the solid immersed in the liquid can be calculated using the formula V = (m - m_liquid) / ρ, where m is the mass of the solid in air, m_liquid is the mass of the solid in the liquid, and ρ is the relative density of the liquid. In this case, the mass of the solid in air was 400 g, the mass of the solid in the liquid was 320 g, and the relative density was 0.8 g/mL. So, the volume of the solid immersed in the liquid was 50 mL.
