A 5 vol% ethanol solution needs to be converted to wt% for the table in the 
CRC Handbook of Chemistry and Physics, 62nd Ed, pg D-207.  
The density of pure alcohol is 0.791 times that of water at 20 C.

Basis 100 ml solution: 
alcohol = 5x0.791 = 3.955 grams
water   = 95x1.00 = 95.000
Total   =           98.955 g

Wt% alcohol = 3.955/98.955 = 0.0400 -> 4.00 wt% alcohol.
