Having obtained the volume of a flask (25.00 cm³), the student emptied the flask, dried it, an 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.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
