Problem PageQuestion A chemistry student needs 10.0g of dimethyl sulfoxide for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of dimethyl sulfoxide is ·1.10gcm-3. Calculate the volume of dimethyl sulfoxide the student should pour out.

9.09cm3

Explanation:

The following data were obtained from the question:

Mass of dimethyl sulfoxide = 10g

Density of dimethyl sulfoxide = 1.10gcm-3

Volume of dimethyl sulfoxide = ?

The density of a substance is simply the mass substance per unit volume of the substance. It is represented mathematically as:

Density = Mass/volume.

With the above formula, we can obtain the volume of dimethyl sulfoxide as follow:

Density = Mass/volume

1.10gcm-3 = 10g / volume

Cross multiply to express in linear form

1.10gcm-3 x Volume = 10g

Divide both side by 1.10gcm-3

Volume = 10g / 1.10gcm-3

Volume = 9.09cm3

Therefore, the volume of dimethyl sulfoxide the student should pour out is 9.09cm3
