Avogadro's constant is the number of:

Explanation

Avogadro's Number (NA) is the number of atoms, molecules, ions, or anything in one mole of the respective substance. As 6.02 x 1023 atoms, molecules, ions, or electrons are present in one mole; therefore, this number is known as Avogadro's number.Only 24g of Mg equals one mole of Mg. Thus, only 24g of Mg has Avogadro's number of atoms.1g of He equals 1/2 mole of He. Thus it has half the number of atoms than Avogadro's number.35.5g of chlorine equals 1/2 mole of chlorine gas. Thus, it has half the number of molecules than Avogadro's number.2g of H equals two moles. Each mole of H atoms has 1 mole of electrons only, so two moles of H have twice the number of electrons than Avogadro's number.
