Determine the molar concentration of ethanol (C2H6O) in a wine that is 14% ethanol by mass. The density of this wine is 0.93 g/cm^3.

Answer 1

a liter of the wine has a mass of 930 g

14% is ethanol ... .14 * 930 = ?

calculate the ethanol mass

divide by the molar mass to find the moles in the liter of wine (molar concentration)
