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

1 answer

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.
