Organic Chemistry is a sub-unit of chemistry which refers to the scientific study of carbon compounds. It focuses on the structure, properties, composition, reactions, of carbon containing compounds.
Example of carbon compounds include salt, alcohol, ethane, methane, butane, benzene, hexane and more.
Each mole of a substance contains 6.02 x 10²³ particles
Atoms of Fe = 4.5 x 6.02 x 10²³
= 2.709 x 10²⁹ atoms
Answer:

Explanation:
Each value on the scale represents 10 times the previous value.
Subtract 1 from 6, so 10 to the power of 5 is the difference.
The number of atoms of each element :
C : 1 atom
H : 3 atoms
Br = 1 atom
<h3>Further explanation</h3>
Given
Bromomethane-CH₃Br
Required
The number of atoms
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
The number of atoms in a compound is generally indicated as a subscript after the atom
C : 1 atom
H : 3 atoms
Br = 1 atom
Total 5 atoms
Answer:
Different materials have different densities. So it is False
