Question

Siddharth was asked to prepare 250 ml of both 2 molar HCl solution and 2 molar sodium hydroxide solution. What volume of concentrated HCl(18 M) and mass of sodium hydroxide should he take in order to prepare these two solutions.​

Answer 1

molarity = no. of moles of solute / 1 liter .

* one moles of sodium hydroxide = 40 gm of sodium hydroxide.

so we can said ; if want prepare 1 molar NaOH solution then we need 40 gm NaOH dissolve in one liter of water so it became one 1 molar NaOH solution.
