Answer:
4.816x10²⁴atoms
Explanation:
the number of moles of oxygen is 8
let x be number of oxygen atoms
recall that 1 mole=6.02x10^23 atoms
therefore, 8 moles =x
cross multiply
8 x 6.02 x 10^23 = x
x = 4.816 x 10²⁴atoms
The answer is electrical energy
Answer: Non covalent interactions.
Explanation: The non covalent interactions can be defined as the interaction among molecules based on the variation among the electromagnetic radiations.
These molecules are not attached to each other based on the sharing of the electrons.
These interactions are Van der Waals, electrostatic, hydrophobic interactions.
The interaction among the molecules is important in order to maintain the three dimensional structure of compound such as carbohydrates and protein molecules.
The chemical formula of hydrocortisone valerate is C26H38O6. First, we determine the molar mass of the substance by adding up all the products of the number of atoms and the molar mass of atoms as shown below.
molar mass = 26(12) + 38(1) + 6(16) = 446 g/mol
Since, there are 26 atoms of carbon in each molecule, the mass of carbon in each mole is
mass of carbon = (26)(12) = 312
Obtaining the percent by mass of carbon,
% by mass of carbon = (312/446) x 100 %
= 69.955%
Thus, the percent by mass of carbon in hydrocortisone valerate is approximately 69.96%.
