The following procedure was used to determine the volume of a flask. The flask was weighed dry and then filled with water. If the masses of the empty flask and filled flask were 56.12 g and 87.39 g, respectively, and the density of water is 0.9976 g/cm^3, calculate the volume of the flask in cubic centimeters.

    31.345 cm³

    Explanation:

    Given:

    Mass of the empty flask, m = 56.12 g

    Mass of the flask filled with water, M = 87.39 g

    Density of the water, ρ = 0.9976 g/cm³

    now,

    the mass of water filled in the flask, Mw = M - m = 87.39 - 56.12 = 31.27 g

    also,

    Density = mass / volume

    thus, for water

    0.9976 = 31.27 / volume

    or

    volume of water = 31.345 cm³

    hence, the volume of flask is the volume of water filled = 31.345 cm³
