An ethanol solution is prepared by dissolving 10 mL of ethanol (C2H5OH) (density: 0.800 g/ml) in a sufficient volume of water to produce 100 mL of solution with a density of 0.982 g/mL. What is the concentration of ethanol in this solution expressed as:
a. Volume percent
b. Mass percent
c. Mass/volume percent
d. Mole fraction of Ethanol
e. Molarity
f. Molality
