Question

Determine of mass percentage of water in an apple

Answer 1

The water content in a medium-sized apple is 84 percent, according to WebMD. Fruits with higher levels include watermelon, which has a 92 percent water content.

Pears have the same 84 percent water content as apples, states SFGate. In addition to providing nutrients, high-water fruits also regulate the human body, which is 60 percent water. Water in the body is crucial in transporting such elements as oxygen and glucose to the muscles. Water also regulates body temperature and ensures that waste is properly processed. Water-based fruits are more effective than water and sports drinks because fruit also replaces the essential nutrients that are drained during exercise, according to a study by the University of Aberdeen Medical School cited by SFGate. Water fruits also contain few calories and satisfy hunger quickly.

Answer 2

Most fruits have high water than the solid percentage. Apples have a dry mass that weighs less than the mass of water.

A fool-proof method to check the water percentage of an apple is to weigh a whole apple first. Let the weight be recorded as A1 gms.

Heat the apple so that the water evaporates from the water and re-weigh the apple. Let this weight be A2 gms.

The difference between A1 and A2 is the water content in the apple.

Usually, an apple has 65% of water content.
