Question

A healthy person has about 175. mg of cholesterol per 100 mL of blood. If the total blood volume of that individual is 4.50 L, how many grams of total blood cholesterol does the individual contain?

Answer 1

There are
`7.875` grams of cholestrol in
`4.50`L of blood

Step-by-step explanation:

Given-

Volume of blood
`= 4.50` liters

One liter is equal to one thousand milliliters.

Amount of cholesterol in
`100` mL of blood
`= 175`mg

Amount of cholesterol in
`1` mL of blood
`= (175)/(100) \\= 1.75`mg

Amount of cholestrol in
`4.50`L of blood is equal to

`1.75 * 4500\\= 7875`mg

`1` mg
`=(1)/(1000)`grams

So, there are
`7.875` grams of cholestrol in
`4.50`L of blood
