A chemist will use a sample of 30 g of ethanol (CH3CH2OH) in an experiment. In one to two sentences, make and justify a claim about the number of moles of ethanol the chemist will use.
1 answer
The chemist will use approximately 0.67 moles of ethanol in the experiment, as the molar mass of ethanol is 46.07 g/mol. This calculation is derived from dividing the given mass of ethanol (30 g) by its molar mass.
