What is the heat of formation of NaOH which molarity is 202

What is the heat of formation of NaOH which molarity is 2.02? If heat of formation of NaON, which molarity is M 1.00, -469.6, is heat of formation of M 2.02 NaOH = 2*469.6?

heat of formation of NaON, which molarity is M 1.00 = -469.6 unit /mol

for 2.02 molarity = -469.9*2.02 unil /mole = 939.2
