Question

A stone has a mass of 100 grams and a volume of 10ml water has a density of 1 g/ml will the stone sink or float?

Answer 1

the rock will sink because the density of the rock is 10g/mL and then density of the water is 1g/mL so because the waters density is lower the rock will sink but if the rock had less density then the water it will float.

Answer 2

Density = Mass / Volume

Density of stone = 100 / 10 = 10 g/mL

If the density is higher than water, then the object will sink. If the density of the object is lower than water, then the object will float.

Since the density of the rock is 10g/mL and the density of the water is 1g/mL, the stone will sink.
