Spirytus Polish Vodka is 96% alcohol by volume.
How much cranberry juice would have to be added to 500mL of this vodka resultant mixture with an alcohol content of 12%
Volume of alcohol= 0.96 x 500mL
Total Volume: 500+C, where C is volume of cranberry juice
0.96 x 500/(500 + C) = 0.12
0.96 x 500 = 0.12 x ( 500 + C)
0.96 x 500/0.12 - 500= 3500
So you must add 3500 mL of cranberry juice
b. How much Smirnoff Vodka with an alcohol content of 37.5% by volume would have to be added to 500mL of Smirnoff Vodka to get a resultant mixture of 55% alcohol.
