What is the concentration of water in liquid (percent)

Hello!

Reading the worksheet shows you how to find the concentration of liquid water in a substance, but when converting a decimal to a percentage, remember that ALL percentages are out of 100, so, we multiply the decimal by 100 to convert it into a percentage.

Liquid A: total amount: 10 millimeters & amount of water: 7 millimeters

7/10 = 0.7 × 100 = 70%

Liquid B: total amount: 100 millimeters & amount of water: 92 millimeters

92/100 = 0.92 × 100 = 92%

Liquid C: total amount: 15 millimeters & amount of water: 13 millimeters

13/15 = 0.867 × 100 = 86.7%

Liquid D: total amount: 28 millimeters & amount of water: 22 millimeters

22/28 = 0.786 × 100 = 78.6%
