Question

4g/l solution of NaOH is given. The molarity of the solution is ___​

Answer 1

NaOH has a molar mass of 40g/mol . So now, we need to convert 100mL into L . Since we have now the desired units, we plug them into the equation. So, the molarity of the solution will be 1M .

Answer 2

Answer:

hope it help you plsss mark as brainlest

Explanation:

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.
