1. The mass of the water is 8.13 g.

2. The density of the water is 1 g/mL

Density is related to mass and volume by the following equation:

<h3>Density = mass / volume </h3>

<h3>1. Determination of the mass of water. </h3>

Mass of cylinder = 56.98 g

Mass of cylinder + water = 65.11 g

<h3>Mass of water =? </h3>

<h3>Mass of water = (Mass of cylinder + water) – (Mass of cylinder) </h3>

Mass of water = 65.11 – 56.98

<h3>Mass of water = 8.13 g</h3>

Thus, the mass of the water is 8.13 g

<h3>2. Determination of the density of water. </h3>

Mass of water = 8.13 g

Volume of water = 8.15 mL

<h3>Density of water =? </h3>

Density = mass / volume

Density = 8.13 / 8.15

Density of water = 0.998 g/mL

<h3>Density of water ≈ 1 g/mL </h3>

Therefore, the density of the water is 1 g/mL
