Question

4 gram NaOH ko 100 ml water me ghola gya prapt solution ki normalta kya hogi?

Answer 1

Normality =molarity ×n-factor

n-factor of NaOH is 1

molarity =number of moles of solute /volume of solution in litre

moles =4/40=0.1

volume in litre =100/1000=0.1 L

molarity=0.1/0.1=1

Normality=1×1=1


thanks
