The number of moles of hydrogen peroxide is  0.402 moles

Calculation:

Water volume, V = 20.1 mL.

MnO4 has a molarity of 0.020 M.

To Locate:

the quantity of potassium permanganate solution in moles.

Solution:

Molarity is determined by:

M = Volume in liters/Numbers of moles

0.020=n/20.1

n=0.020×20.1

n=0.402moles

As a result, 0.402 moles of potassium permanganate solution are present.

How many moles are there in chemistry?

6.02214076 x 1023 of any chemical unit, such as atom, molecules, ions, and others, constitute a mole. Due to the large number of atoms, molecules, or other components that make up any substance, the mole is a useful measure to utilize.
