Question
Having obtained the volume of a flask (25.00 cm³), the student emptied the flask, dried it, and
filled it with an unknown liquid whose density she wished to determine. The mass of the
stoppered flask when completely filled with liquid was 47.867 g. The mass of the empty
stoppered flask was 26.192 g.
Find the density of the liquid. (in g/cm³)
(a)
First we need to find the mass (in g) of the liquid by determining the difference.
mass of liquid = g
(b)
The density of a pure substance is equal to its mass divided by its volume:
density =
mass
volume
Since the volume of the liquid equals that of the flask, we know both the mass and volume of
the liquid and can easily find its density. Calculate the density (in g/cm³) of the unknown
liquid.
density of liquid=
