Question 1

What is a Avogadro Calculator?

Accepted Answer

Avogadro's number (6.022 × 10²³ mol⁻¹) is the number of particles in one mole of any substance, connecting the macroscopic gram scale with the atomic scale.

Question 2

How does the Avogadro Calculator work?

Accepted Answer

Particles = Moles × 6.022×10²³ Then: Moles = Mass / Molar mass Then: Molar mass H₂O = 18.015 g/mol Then: 1 mole of any ideal gas at STP = 22.4 litres.

Question 3

Can you give an example of how to use the Avogadro Calculator?

Accepted Answer

Example: Input 36g of water (H₂O) gives a result of 36/18.015 = 2 moles; 2 × 6.022×10²³ = 1.204×10²⁴ molecules.
