5 fl ox of a 2% alcohol solution was mixed with 11 lf oz of a 66% alcohol solution. Find the concentration of the new mixture
.
Amount of acid from 2% solution:
.02*5 = 0.1 oz
.
Amount of acid form 66% solution:
.66*11 = 7.26 oz
.
Total amount of acid: 0.1+7.26 = 7.36 oz
.
Concentration:
7.36/(5+11) * 100
= 7.36/16 *100
= 46%
