The term "proof" is defined as twice the percent by volume of pure ethanol in solution. Thus, a solution that is 95% (by volume) ethanol is 190 proof. What is the molarity of ethanol in a 92 proof ethanol/water solution?

	density of ethanol	= 0.80 g/cm³
	density of water	= 1.0 g/cm³
	mol. wt. of ethanol	= 46 g/mol

▸ 0.46 M

▸ 0.80 M

▸ 0.92 M

▸ 8.0 M

▸ 17 M
