After examining the full bottle (200-gram mass), the inspector noticed a small amount of a crystalline substance in the bottom. Like all good movie inspectors he tastes a bit...and it has a sweet taste...and later he feels very energized. He had a 85g sample of the vodka evaporated and was left with 5.5g of white substance. What was the percent by mass of the white substance? What could have been done to the vodka to get the white substance to dissolve?
