Question

How many atoms are there in 7.8g of potassium element

Answer 1

12.00 g C-12 = 1 mol C-12 atoms =6.022 × 1023 atoms. The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023). Calculate the number of atoms in 2.45 mol of copper. A silver ring contains 1.1 x 1022 silver atoms.


hope iy helps
