How many formula units are there in 2.45 moles KCL?

14.75 * 10²³ formula units

Explanation:

Given dа ta:

Number of moles = 2.45 KCl

Formula units = ?

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 example,

1 mole of water = 6.022 * 10²³ formula units of water

For 2.45 moles of KCl:

2.45 * 6.022 * 10²³ formula units

14.75 * 10²³ formula units
