Final answer:
Estimating based on the average water content of the human body and converting 150 pounds to kilograms, approximately 42 liters of water are contained in a person weighing 150 pounds.
Step-by-step explanation:
For a person weighing 150 pounds, the amount of H2O (water) present in the body can be estimated by considering that water makes up 50-70% of the body's weight. Since fat content can affect this percentage, we'll use an average value of 60% for a general estimation. To convert 150 pounds to kilograms (since 1 liter of water is roughly equivalent to 1 kilogram), we multiply 150 by 0.453592, which gives us approximately 68 kilograms. Therefore, 60% of this weight in water equals 40.8 liters, which we can round to the closest answer provided, 42 liters (option c).
