Answer» molarity is no. of moles per litre of solution. here mass of NaOH = 4g so, moles will be 4/40 = 0.1 volume of solution is 250ml = 0.25L so, molarity = 0.1/0.25 = 0.4M thank u so much

Answer»

molarity is no. of moles per litre of solution.

here mass of NaOH = 4g so, moles will be 4/40 = 0.1

volume of solution is 250ml = 0.25L

so, molarity = 0.1/0.25 = 0.4M

thank u so much
