100 mL of water is already in the calorimeter. Use the density of water at 25°C (0.998 g/mL) to determine the mass

To determine the mass of 100 mL of water using its density, you need to multiply the volume of water by its density.

Given:
Volume of water = 100 mL
Density of water at 25°C = 0.998 g/mL

To find the mass, use the formula:

Mass = Volume x Density

Substitute the given values:

Mass = 100 mL x 0.998 g/mL

Now, multiply the volume by the density:

Mass = 99.8 g

Therefore, the mass of 100 mL of water is 99.8 grams.
