The molarity is defined as a number of moles of a certain substance in 1L of a solution. Molarity can be found by the following formula:
M = n / V = m / (Mr × V)
where n – number of moles, V – volume of a solution, m – mass, Mr – molecular mass.
The molecular weight of NaOH equals:
Mr(NaOH) = 23 g/mol + 16 g/mol + 1 g/mol = 40 g/mol
As a result, the molarity of NaOH can be calculated as following:
M(NaOH) = m / (40 g/mol × V).
