To determine the volume of water, we need to account for the density of water, which changes with temperature. However, at 25.4°C, the density of water is close enough to 1 g/mL for practical purposes. Therefore, we can approximate the volume of water to be the same as its mass.
Given:
Mass of water = 19.5487 g
Volume of water = Mass of water
Therefore, the volume of water is approximately 19.5487 mL.
