How many particles are there in 1.43 g of a molecular compound with a gram molecular mass of 233 g?

3.7× 10²¹particles

Explanation:

Given data:

Mass of compound = 1.43 g

Gram molecular mass = 233 g

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 1.43 g of compound:

one mole =  6.022 × 10²³ particles

1.43 g × 6.022 × 10²³ particles  / 233 g

0.037× 10²³ particles

3.7× 10²¹particles
