I got D but I am reworking it now, think my conversion was wrong.

2. And this one I couldnt figure out how to set it up exactly :

An individual suffering from high cholesterol level in her blood has 232mg of cholesterol per 100 mL of blood. If the total blood volume of the individual is 5.2l, how many grams of total blood cholesterol does that individual contain?

Is the start 232mg/100mL then convert from there?

10 points!
