avogadros number was calculated by determining the number of atoms in\n12.00 g of carbon - 12.\n14.00 g of…

Brief Explanations:

Avogadro's number ($6.022\times 10^{23}$) is defined as the number of atoms in 12.00 g of carbon - 12. One mole of any substance contains Avogadro's number of entities. The molar mass of carbon - 12 is 12 g/mol, so 12.00 g of carbon - 12 is exactly 1 mole.

Answer:

12.00 g of carbon-12.
