Question

4g NaoH dissolve in 500ml solution calculate molarity​

Answer 1

A solution is prepared by dissolving 4g of NaOH to give 500 mL of it. Calculate the molarity of the solution. Molarity of solution (M)=Moles of NaOHVolume of solution in litres=0.1 mol0.5L=0.2mol L-1=0.2M.

Answer 2

Answer:

Moles of NaOH=molarmassmass=404=0.1

500ml≈500g

molality==massofsolvent(kg)molesofsolute=5000.1×1000

m=2
