If a person has a mass of 62 kg, how many pounds of water does she have in her body? And it gives the typical adult body containing 51% water

instead of .6, multiply by .51
kg water = 62 kg x 0.51 = ??
Then convert kg to lbs.
Ok so it would be 69.7221 lb or 70lb since it only wants two sig figs
To find out how many pounds of water a person has in their body, we need to know two things: the person's mass and the percentage of water in the typical adult body.
First, let's calculate the total amount of water in the person's body. We can do this by multiplying the person's mass (in kilograms) by the percentage of water in the body.
Given:
Mass = 62 kg
Water percentage = 51%
1. Calculate the total amount of water:
Total water = Mass(in kg) * Water percentage / 100
Total water = 62 kg * 51 / 100
Total water = 31.62 kg
Now that we have the total amount of water in kilograms, we can convert it to pounds.
2. Convert kilograms to pounds:
1 kg = 2.20462 pounds
Total water in pounds = Total water in kg * 2.20462 lbs/kg
Total water in pounds = 31.62 kg * 2.20462 lbs/kg
Total water in pounds = 69.68 lbs
Therefore, a person with a mass of 62 kg would have approximately 69.68 pounds of water in their body.
