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 dа ta:

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
