The concentration of cholesterol (C27H46O) in blood is approximately 5.0mM. How many grams of cholesterol are in 315mL of blood
ASHA 777 [7]

The weight of cholesterol is 0.6 g.

Here use the concept of molarity.

<h3>What is molarity?</h3>

The amount of a substance in a specific volume of solution is known as its molarity (M). The moles of a solute per liter of a solution is known as molarity.

Molarity = no. of moles/volume (in L)

<h3>Calculation:</h3>

Given,

Molarity, M = 5.0 mM = 5 × 10⁻³ M

Volume, V = 315 mL = 315 × 10⁻³ L

To calculate,

Weight of cholesterol =?

We know that,

Molecular mass of cholesterol, C₂₇H₄₆O = 386

No. of moles = weight/ molecular mass

The formula is modified as,

Molarity = weight of cholesterol/ (molecular mass) (Volume)

Put the values in the formula,

5 × 10⁻³ = weight of cholesterol/ (386) (315 × 10⁻³)

Weight of cholesterol = 5 × 10⁻³  (386) (315 × 10⁻³)

                                    = 0.6 g

Hence, the weight of cholesterol is 0.6 g.

Explain the meaning of the symbols as they are used in this expression.
Dmitrij [34]

Answer:

  • A, B, C and D are: elements or molecules
  • A and B are: reactants
  • C and D are:  products

Explanation:

The expression "A + B <--> C + D" represents a chemical equation. A chemical equation represents the "mixture" of molecules or elements that will react and form other molecules and elements, so we can say that A, B, C and D represent molecules or elements.

But not only that. In a chemical equation, the elements and molecules that are before the symbol "<-->" represent the reagents in the equation. Therefore, A and B are the reagents. The elements or molecules found after the symbol "<-->" are the products of the reaction. Therefore, C and D are the products.
