How many molecules are there in 36 g of fef3?

36 g of FeF₃ contain 1.92 ×10²³ molecules.

Explanation:

Given data:

Mass of FeF₃= 36 g

Number of molecules = ?

Solution:

First of all we will calculate the molar mass of FeF₃.

Molar mass of FeF₃ = 55.845 + 18.998 ×3 = 112.84 g/mol

The number of molecules will be determine through the Avogadro number.

The number 6.022×10²³ is called Avogadro number and it is the number of atoms or molecules in one gram of atoms of an element or one gram molecules of a compound.

112.84 g of FeF₃ = one mole of  FeF₃ = 6.022×10²³ molecules

36 / 112.84 × 6.022×10²³ molecules = 1.92 ×10²³ molecules

36 g of FeF₃ contain 1.92 ×10²³ molecules .
