Z 1 mola (2 * 23 g + 16 g = 62 g) tlenku sodu powstaje 2 mole NaOH.
Policzymy, ile moli NaOH powstaje z 50 g tlenku:
62 g tlenku--------------------------------2 mole NaOH
50 g tlenku--------------------------------x (moli NaOH)
x ≈ 1,6 mola NaOH
Liczymy stężenie molowe roztworu (Cm):
Cm = 1,6 mola / 0,5 dm³ = 3, 2 mol / dm³
