Question

How many molecules of hydrogen fluoride (HF) are in (8.5x10^-2) moles of hydrogen fluoride (HF)?

Answer 1

Avogadro's numbers are used to convert the moles, atoms, and molecules. There are 51.17 × 10²¹ molecules in 8.5 x 10⁻² moles of HF.

What is Avogadro's number?

Avogadro's number converts the moles into molecules with the help of the value of the Avogadro's number as 6.02 x 10²³.

We know that 1 mole of HF has 6.02 x 10²³ molecules

Then, 8.5 x 10⁻² moles of HF will have:

(8.5 x 10⁻²) × 6.02 x 10²³ = 51.17 × 10²¹ molecules.

Therefore, 51.17 × 10²¹ molecules are present in 8.5 x 10⁻² moles of HF.
