Water has a density of 1.0 g/mL. Calculate the density of each object to determine which of the objects will float in water, and then pick your choice below. Object I: mass = 50.0 g; volume = 60.8 mL Object II: mass = 65.2 g; volume = 42.1 mL Object III: mass= 100.0 g; volume = 20.0 mL I and III ||| I OII and III ||
