1.	5x2=10I)Calculate the molarity of NaOH in the solution, prepared by dissolving 10g inenough water to form 500mL of the solution. Molar mass of NaOH is
Answer» Given:molecular mass=40 g/molvolume of solution= 500ml=0.5 litermass of NaOH=10gFormula: no of moles= given mass/molecular massmolarity=no of moles/volume of solution in literSolution:no of moles=10/40=0.25 molmolarity=0.25/0.5=0.5MTherefore molarity=0.5M
