Answer:
The density of water is 1.00 g/mL.
Step-by-step explanation:
To get the density of water from the given measurements, we must first get the mass of water. We get this by subtracting the mass of the beaker from the mass of the beaker and the water.
105.0 g - 55.0 g = 50.0 g
Now since we have both mass and volume, we can get density. Density is mass over volume, so we can get it by dividing the mass by the volume.
50.0 g ÷ 50.0 mL = 1.00 g/mL
The density of water is 1.00 g/mL.
