Respuesta :
The number of atoms which are present exactly in 12 grams of carbon-12 is called Avogadro's number.
What is Avogadro's number?
Avogadro's number is the number of atoms which are present in 1 mole of any substance and it is equal to 6.022×10²³.
And moles will be calculated as:
- n = W/M, where
- W = given mass
- M = molar mass
Moles of Carbon-12 = 12g / 12g/mol = 1mole
In 1 mole of Carbon-12 = 6.022×10²³ atoms are present.
Hence, the number of atoms in exactly 12 grams of carbon-12 is called Avogadro's number.
