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
