Answer:
It is an example of Arrhenius acid-base reaction.
Explanation:
- In this reaction, water acts as an Arrhenius base because it consumes a proton from sulfuric acid.
- In this reaction, sulfuric acid acts as an Arrhenius acid because it donates a proton to water.
- Lone pair on oxygen atom in water is used to bind the proton obtained from sulfuric acid.
- Proton attached to -OH group in sulfuric acid is being donated because it is loosely bounded to oxygen atom due to high polarity of O-H bond.
- Reaction:
- Mechanism has been shown below.

Explanation:
A mole is the amount of matter or substance that contains the Avogadro's number of particles.
1 mole of a substance = 6.02 x 10²³ atoms
Now solving:
a:
1.2 x 10² atoms ;
Number of moles = = 2.0 x 10⁻²¹moles
b:
3.87 x 10²¹ molecule:
Number of moles = = 6.4 x 10⁻³moles
c. 4.81 x 10¹⁴ molecules:
Number of moles = = 8.0 x 10⁻¹⁰moles
Number of molecules = number of atoms = formula units
