A chemistry student needs 55.0g of carbon tetrachloride for an experiment. by consulting the crc handbook of chemistry and physics, the student discovers that the density of carbon tetrachloride is 1.59·gcm−3 . calculate the volume of carbon tetrachloride the student should pour out.

34.6 cm³

Explanation:

Given data

We can determine the volume of carbon tetrachloride that the student should pour out using the following expression.

ρ = m / V

V = m / ρ

V = 55.0 g / (1.59 g/cm³)

V = 34.6 cm³

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
