E. How many grams of chlorophenol are there in 1.00 litre of a 47.0 mM solution? Show your calculations in full.
(6 marks)

The mass of the chlorophenol  is obtained from the number of moles and the volume of the solution.

Recal that;

Number of moles = concentration of solution * volume of solution

Concentration = 47.0 mM  or 47.0 * 10^-3 M

Volume = 1.00 litre

Number of moles = 47.0 * 10^-3 M * 1.00 litre

Number of moles = 47.0 * 10^-3 moles

Also;

Number of moles = mass/molar mass

mass = Number of moles * molar mass

Mass = 47.0 * 10^-3 moles * 128.6 g/mol

Mass = 6.0442 g
