Molar mass is defined as the mass of a chemical compound present in the grams in the mole of the compound or substance.

The molar mass of the cholesterol is 386.75 g/mol.

Cholesterol is defined as:

Cholesterol is a type of fat found in the human blood and cell membranes. It is a waxy substance and a high level of cholesterol in the blood increases the risk of cardiovascular diseases. Molar mass can be calculated as the product of atomic and molas mass constant. The unit of molar mass is g/mol.

Thus, the correct answer is Option B.

Answer from: trueeriksonweav

386.66 g/mol

Explanation:

To calculate the molar mass of a molecule, you add up the molar masses of its atoms.

Thus, for cholesterol. we get

27C = 27 × 12.011 = 324.297 g

46H = 46 × 1.008 = 46.368

1O = 1 × 15.999 = 15.999

TOTAL = 386.655 g

To two decimal places, the molar mass of cholesterol is 386.66 g/mol

Answer from: Quest

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

$^{m}_{4}x$ and $^{m}_4y$

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

$^{m}_{5}x^{-}$

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be $^{9}_{5}be^{-}$ and $^{9}_{4}be$ .

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
