Question

Calculate the molarity of the solution 5ml
of NaOH in 450 ml solution.​

Answer 1

Answer:

molar mass of NaOH=40g per mole

no. of moles in 5g of NaOH=5/40=0.125

volume of solution=450mL=0.45L

molarity of solution=no.of moles of solute/volume of solution

                             =0.125/0.45

                             =0.277777777778=0.28(approx.)
