Question 2

A synthetic chemist prepares a biodegradable polyamide for drug delivery systems via the condensation polymerisation of 240 molecules of 4-aminobutanoic acid, H2NCH2CH2CH2COOH\text{H}_2\text{NCH}_2\text{CH}_2\text{CH}_2\text{COOH}H2​NCH2​CH2​CH2​COOH.

Determine the relative molecular mass, MrM_rMr​, of the resulting linear polyamide.

(Use the following relative atomic masses: H=1.0\text{H} = 1.0H=1.0, C=12.0\text{C} = 12.0C=12.0, N=14.0\text{N} = 14.0N=14.0, O=16.0\text{O} = 16.0O=16.0)
