13. Calculate the molarity of a solution obtained bymixing 4g of NaOH in 250 ml of solution. |
|
Answer» Molarity(M) = w× 1000 / GMW× V where, w = given weight of the solute = 4gGMW = Gram Molecular Weight of the solute = 40gV = Volume of the solution in ml. = 250 ml So, M of NaOH = 4× 1000 / 40× 250 = 0.4 M |
