A sample of ethanoic acid (C2H4O2) has a mass of 60 g. Calculate the number of moles of ethanoic acid in the sample. What is the relative formula mass of ethanoic acid?

The number of moles of ethanoic acid in the sample is 1. The relative formula mass of ethanoic acid is 60 g/mol.

This question assesses the ability to calculate moles from mass using the relative formula mass, reinforcing the concept of moles in chemistry. This response is aligned to Carboxylic acids because it explains represent carboxylic acids in displayed, structural and molecular formula forms using the correct AQA GCSE Chemistry organic context. Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.
