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.

Answer 1

The chemist will be using approximately 0.75 moles of ethanol in the experiment, as the molar mass of ethanol is 46 g/mol and 30 g is close to 1 mole of ethanol. This calculation can help in accurately measuring and analyzing the reaction or process being studied.
