Question

Use the table of molar masses to complete the activity.

A chemist will use a sample of 30 g of ethanol (CHCH2OH) 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

[AI-generated answer — Bot GPT 3.5]

The chemist will use approximately 0.66 moles of ethanol in the experiment. This is calculated by dividing the sample mass (30 g) by the molar mass of ethanol (46.07 g/mol), resulting in 0.65 moles. This value is rounded up to 0.66 moles because it is more accurate to have a slightly higher estimate than a slightly lower one when conducting experiments.
