- upper will śink because it is more dense than water.However the diet soda is less dense than the regular. 30. Density can be calculated by dividing the mass of an object by its volume. Water has a density of 1g/ml. If an object's density is greater than 1 g/ml it will sink and if its density is less than 1g/ml it will float. Object A has a mass of 40g and a volume of 30mL and object B has a mass of 15 g and a volume of 20 mL. What will happen when both objects are placed in water? A. Object A will float because its density is less than water B. Object B will sink because its density is greater than water C. Object A will sink because its density is greater than water D. Objects A and B will both float because their density is the same as water NOV 8.arrow_forward.
