Question

FIND THE MORALITY OF 10 ML OF 0.1 MOLAR NAOH is added to a solution containing 10 ml of 0.5 molar of KOH solution​

Answer 1

Answer:

5

Explanation:

by adding 10ml 0.1 molar solution of NaOH in a 10ml 0.5 molar solution of KOH, the amount of NaOH remains the same but the amount of water it is mixed in, increases.  we can simply ignore the presence of KOH since we have to find the molarity of NaOH

now, volume of solution (in litres)  = 0.02L

no. of  moles of NaOH present in the solution: 0.1

Molarity  = no. of moles/ volume(in L)

0.1/0.02

100/20
