An ethanol–water solution is prepared by dissolving 10.00 mL of ethanol, CH₃CH₂OH (d = 0.789 g/mL), in a sufficient volume of water to produce 100.0 mL of a solution with a density of 0.982 g/mL(Fig. 14-1). What is the concentration of ethanol in this solution expressed as 

(a) Volume percent; 

(b) Mass percent; 

(c) Mass/volume percent; 

(d) Mole fraction; 

(e) Mole percent; 

(f) Molarity; 

(g) Molality?
