A given solution of NaOH contains 4.00 g of NaOH per litre of solution. Calculate the molarity of this solution.

Text Solution

Verified by Experts

Molar mass of NaOH = 40.00 g
4.00 g of NaOH `= (4.0)/(40.00)" mole of NaOH" = 0.1` mol NaOH
`"Molarity"= ("Mole of solute")/("Volume of solution in litre")= (0.1)/(1)= 0.1m`
