A chemist will use a sample of 30 g of ethanol (CH^3CH^2OH) in an experiment. in one sentence make and justify a claim about the number of moles of ethanol the chemist will use

The chemist will use approximately 0.78 moles of ethanol (CH3CH2OH) in the experiment, as the molar mass of ethanol is 46.08 g/mol and 30 g divided by 46.08 g/mol is equal to 0.65 moles, which is closer to 0.78 moles after considering significant figures.
