How many formula units are there in 2.45 moles kcl?

14.75 × 10²³ formula units

Explanation:

Given data:

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
