Question

Write like a 7th grader. Use the equation to answer the question. CH3CHOOH CO2 + CH4. carbon 12.01, hydrogen 10.1, oxygen 16.00. 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

To find out how many moles of ethanol (CH3CH2OH) are in 30 grams, we first need to calculate the molar mass of ethanol. The molar mass is about 46.08 g/mol (12.01 for carbon × 2, 1.01 for hydrogen × 6, and 16.00 for oxygen). So, if we divide 30 grams by 46.08 g/mol, we get about 0.65 moles of ethanol. This means the chemist will use around 0.65 moles of ethanol in the experiment.
