An individual suffering from high cholesterol level in her blood has 242 mg of cholesterol per 100 ml of blood. if the total blood volume of the individual is 5.2 l how many grams of total blood does the individual's body contain?

242 mg of cholesterol is present in 100 mL of blood. If the total blood present in a body is 5.2 L The total body cholesterol can be calculated as follows:

First calculate concentration as follows:

C=\frac{m}{V}=\frac{242 mg}{100 mL}=\frac{242 g}{100 L}=2.42 g/L

Now, total volume is 5.2 L thus, mass will be calculated as follows:

m=C×V=2.42 g/L×5.2 L=12.584 g

Thus, the grams of blood cholesterol in human body will be 12.584 g.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
