Calculate the molarity of 20.5 g of NaOH in 400. mL of an NaOH solution.
Express your answer with the appropriate units.
Molarity is defined as number of moles of solute per liter of solution
Molarity =number of moles/Volume in liter
Molar mass of NaOH=40 g/mol
Number of mole of NaOH=g of NaOH/Molar mass of NaOH
=20.5 g /40 g/mol
=0.512 mol
Volume =400ml=0.4 L
Molarity =0.512mol/0.4 L
=1.28 M
The molarity of given solution is 1.28M
