Answer:
6.02 x 10²²molecules
Explanation:
Given parameters:
Mass of CO₂ = 4.4g
Unknown:
Number of molecules in CO₂ = ?
Solution:
To find the number of molecules in the given mass, we have to find the number of moles in the compound first;
Number of moles = 
Molar mass of CO₂ = 12 + 2(16) = 44g/mol
Insert the parameters and solve;
Number of moles = 
= 0.1mol
1 mole of a substance contains 6.02 x 10²³molecules
0.1 mole of CO₂ will contain 0.1 x 6.02 x 10²³molecules
= 6.02 x 10²²molecules
Explanation :
The region around a charge in which an electrostatic force is experienced is called electric field. It is also defined as an electrostatic force per unit electric charge.
Electric field lines are the imaginary lines to represent the electric field. The field lines always start form positively charged particle and terminate at the negatively charged particle.
For a positive charge, field lines are outwards while for a negative charge field lines are inwards.
For a system of two negatively charged particles, the electric field lines are shown in the attached figure.
According to Coulomb's law, the electrostatic force between two charged particle is given by :
where,
r is the distance between two charges. The electrostatic force is inversely proportional to the square of the distance.
So, if the charged particles are moved farther apart, the electrical force would decrease.
