You freeze 92g of water, and it becomes a cube of ice.

a. What is the mass of the ice cube?
b. The cube's volume os 100cm3. What is it's density?
c. Will the ice cube float or sink in water?

a. The mass doesn't change; it's still 92 g

b. density = mass/volume = 92g/100cm3

c. Is the density of the ice cube less than or greater than the density of water? If it is less than, the ice cube will float. If it is greater than, the ice cube will sink.

A perfectly square ice cube measures 3cm on each side. It has a mass of 24.6g

a. To find the mass of the ice cube, we use the given information that 92g of water has been frozen. Since water and ice have the same density, the mass of the ice cube will also be 92g.

b. Density is defined as mass divided by volume. In this case, the mass of the ice cube is 92g, and the volume is given as 100cm³. Therefore, we can calculate the density by dividing the mass by the volume:

Density = Mass / Volume = 92g / 100cm³

c. To determine whether the ice cube will float or sink in water, we need to compare the density of the ice cube to the density of water. The density of water is approximately 1g/cm³. If the density of the ice cube is less than the density of water, it will float; otherwise, it will sink.

From part b, we know that the density of the ice cube is 92g / 100cm³. Since this is less than the density of water (1g/cm³), the ice cube will float in water.
