WebThe equation says that 1 mole of NaOH reacts with 1 mole of HCl to make a neutral solution. Therefore number of moles of HCl = 2.50 x 10 -3 This is contained in 20.0 cm -3 of HCl. Number of moles in 1000 cm -3 (1 dm 3) = 1000/20.0 x 2.50 x 10 -3 = 0.125 Concentration of HCl = 0.125 mol dm -3 WebThe symbol for the unit mole is mol. One mole of a substance contains the same number of the stated particles, atoms, molecules, or ions as one mole of any other substance. The number of atoms, molecules or ions in a mole (1 mol) of a given substance is the Avogadro constant. The value of the Avogadro constant is 6.02 x 1023 per mole.
