is this for mathh? and can u explain more

Answer 2

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.
