How much water is in the human body if its mass is 28.1 kg?

In the mass of the human body, most of it belongs to water, and therefore the need of human organisms for water is much higher than the need for food.

Determination of its exact amount depends on age, different water content in internal organs, health.

With normal body weight, without excessive thinness or excess kilograms, the amount of water is equal to about two-thirds of the total body weight. Therefore, with a mass of 28.1 kg, we calculate the amount of water by dividing 28.1 by three, and multiplying the result by two. We get 18.73 liters.
