The mole

The mole The mole is a common unit used to represent the quantity of a chemical substance and is the amount of that substance that contains 6.2023×1023 particles (Avogadro’s constant). Number of moles =mass of substance/R.F.M   Calculating masses Na2SiO3 R.F.M= (R.A.M Sodium x 2) + (R.A.M Silicon) + (R.A.M Oxygen x 2) R.F.M= (23×2)…
