Answer:
55.3 × 10²³ molecules
Explanation:
Given data:
Number of moles of C₁₁H₁₂O₂₂ = 9.18 mol
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
For given data:
9.18 mol × 6.022 × 10²³ molecules /1 mol
55.3 × 10²³ molecules
Answer:
Explanation:
The question is based on the concept of the cleavage of bonds. In the process of the reaction the breaking of bonds is required. The cleavage of the bonds make the bonded electrons free to involve in the reaction process.
Fundamentals:
The cleavage of the bond can be done in two ways: homolytic or heterolytic. The heterolytic cleavage occurs when the shared electrons of the covalent bond are taken away by either of the atom. The heterolytic cleavage results in generation of the charged molecules. On the other hand, the homolytic cleavage is the cleavage in which the shared pair of the electrons are equally distributed, resulting in generation of free radicals.
It contains one mol of carbon atoms. For the better calculating in the chemical reaction, we often use the mol as unit to describe the amount. Carbon is consists of carbon atoms. And the mol number is related to the mass of atoms. The molar mass of carbon is 12 g/mol. So the answer is 1 mol carbon atoms.

Answer:
a) 74.87 % carbon
Explanation:
Molecular mass of CH₄ is 16.042 g / mole.
Now we divide the following reasoning for 1 mole of methane:
if in 16.042 g of CH₄ there are 12.01 g of carbon
then in 100 g of CH₄ there are X g of carbon
X = (100 × 12.01) / 16.042= 74.87 % carbon
