Understanding Density: Calculating Mass of Water in a Calorimeter

How do you calculate the mass of water in a calorimeter filled with 75 mL of water at 25°C?

Given the volume of water, temperature, and density, what is the mass of water in this scenario?

Answer:

The mass of water in a calorimeter filled with 75 mL of water at 25°C and a density of 0.998 g/mL is 74.85 grams.

Explanation:

To calculate the mass of water at 25°C, given that the calorimeter has been filled with 75 mL of water and the density of water at this temperature is 0.998 g/mL, you can use the formula:

Mass = Volume × Density

In this case, the volume is 75 mL and the density is 0.998 g/mL. Multiplying these two values together gives us:

Mass = 75 mL × 0.998 g/mL = 74.85 grams of water

This calculation determines the amount of water present in the calorimeter at 25°C.
