The Mass of Ice Calculation

What is the mass of 2.5 cm3 of ice at its freezing point?

Answer: The answer is option B

Explanation: The mass of a substance can be found using the formula mass = Density × volume. In this case, the density of ice at its freezing point is 0.917 g/cm3 and the volume is 2.5 cm3. So, the calculation will be 0.917 × 2.5 = 2.2925 which is approximately 2.3 g. Thus, the correct answer is 2.3 g.

Understanding the Mass of Ice Calculation

When calculating the mass of a substance, it is essential to know both the density and volume of the material. In this scenario, we are dealing specifically with ice at its freezing point, which has a density of 0.917 g/cm3. The given volume of ice is 2.5 cm3.

The formula used for calculating the mass of a substance is: mass = Density × volume

By substituting the values into the formula, we get: mass = 0.917 × 2.5 = 2.2925 g. Rounding up, we can determine that the mass of 2.5 cm3 of ice at its freezing point is approximately 2.3 g.
