2. To mix an ultrasonic cleaning solution, 10 milliliters (mL) of concentrated cleaner is added to 500 mL of distilled water. What is the ratio of cleaner to

water?

of 10

ratio of cleaner to water = 1 : 50

Explanation:

volume of ultrasonic cleaning solution = 10 mL

volume of distilled water = 500 mL

∴ ratio of cleaner to water = 10 : 500

simplifying further

10 : 500 = 1 : 50

∴ ratio of cleaner to water = 1 : 50
