When completely filled with water, the beaker and its contents have a total mass of 326.75 g. What volume does the beaker hold? Use?=1.00 g/mL as the density of water.

0.003060 cm³

Explanation:

Mass of water = m = 326.75 gram

Density of water = ρ = 1.00 g/mL = 1 g/cm³

density = mass / volume

⇒volume = density / mass

⇒volume = 1 / 326.75

⇒Volume = 0.0030604 cm³

∴ Volume held by beaker = 0.0030604 cm³

Here the combined mass of the beaker and water is given so the volume found will be of the beaker as well as the liquid. But, it can be seen that the volume is so small that subtracting the beaker mass would have negligible effect.
