What is Relative Molecular Mass of Amidosulphuric Acid about?

The document describes an experiment to determine the relative molecular mass of amidosulphuric acid. Amidosulphuric acid was titrated with a sodium hydroxide solution of a known concentration. Calculations based on the moles of acid and base used yielded a relative molecular mass of 94.18 for amidosulphuric acid. However, the theoretical value is 97.1. Sources of error in the experiment include subjective determination of the color change point and loss of acid during transfer. Improving procedures such as
