The mass of an empty container is 84 g. the mass of the container filled with water is 114g. what is the volume of the container? the density of water is 1 g/cm^ 3 ? . answer in units of cm^ 3 .

30 cm³

Explanation:

mass of water = mass of the container filled with water - mass of the empty container

mass of water = 114 - 84 = 30 g

density = mass / volume

volume = mass / density

Now the volume of the container is equal to the volume of water which filled the container.

volume of water = volume of the container = 30 / 1 = 30 cm³
