Use the table of molar masses to complete the activity. Element Molar Mass (g/mol) carbon 12.01 hydrogen 1.01 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.
The chemist will use approximately 1.47 moles of ethanol in the experiment. This calculation can be made by adding the molar masses of the elements in ethanol (12.01 for carbon, 1.01 for each hydrogen, and 16.00 for oxygen) to find the molar mass of ethanol (46.08 g/mol), and then dividing the given mass of ethanol by its molar mass.
