How many atoms are present in 23.0 g of carbon?

Answer: 6.0225X10^23

Explanation:

Number of atoms in 24g of carbon

We know that Carbon has atomic mass equal to 12g, I. E. One mole of carbon atom weighs 12g. We know that one mole of any substance contains 6.0225X10^23 particles (atoms, molecules, ions, etc.). Thus 12g of Carbon contains 6.0225X10^23 atoms of Carbon
