Question

Calculate molarity of 100ml naoh soln having 12gm naoh in 500ml of water

Answer 1

Answer:

Explanation:

Total volume=100+50=150ml

Number of moles=Mass/Molar mass=12/40

Molarity=Number of moles/(Volume of solution in litres)=(12/40)/(150/1000)=2

So, molarity of the given NaOH solution is 2.

Answer 2

Answer:

total volume 100 + 50 =150 ml
