Question

Find the number of atoms in following :

a. 1 mole of Na atom.

b. 1 mole of Hydrogen atom

c. 1 mole of Hydrogen molecule

d. 10 mole of Oxygen atom

e. 10 mole of Oxygen gas.

f. 0.1 mole of Calcium Carbonate molecules.

g. 0.01 mole of Hydrogen sulphide molecule.​

Answer 1

Answer:

One mole of atoms of oxygen has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 6.02 X 1023 atoms of oxygen* 10 is your d) answer

hen, multiply the number of moles of Na by the conversion factor 6.02214179×1023 atoms Na/ 1 mol Na, with 6.02214179×1023 atoms being the number of atoms in one mole of Na (Avogadro's constant), which then allows the cancelation of moles, leaving the number of atoms of Na
