Asked by Ms Fatimah

In an experiment to determine the relative density of a plastic cork stopper, the mass of a glass cork stopper in water is 6g, while that of the glass cork stopper in water and plastic cork stopper in air is 12g. What is the mass of both cork stoppers in water if the relative density of the plastic cork stopper is 0.75?

Really is the same as your other problem.
