Answer:
An adult has approximately 5.4 liters of water in their blood.
Explanation:
If human blood consists of 90% water and an adult has nearly 6 liters of blood, we can calculate the amount of water in the blood as follows:
Amount of water in the blood = 90% of 6 liters
= 0.9 x 6 liters
= 5.4 liters
Therefore, an adult has approximately 5.4 liters of water in their blood.
