The volume percentage of 18 L of isopropanol in 45 L of water is 28.57%
Total solution = volume of water + volume of isopropanol
Total solution = 18L + 45L
Total solution = 63L
Volume of isopropanol = 18L
% volume of 18L isopropanol = 18/63 * 100
% volume of 18L isopropanol = 1800/63
% volume of 18L isopropanol = 28.57%
