Question

what is the molarity of naoh when 40g of naoh are dissolved in 1liter of water​

Answer 1

Answer:

1M

Hence, the Molarity of NaOH is 1M.

Explanation:

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

one mole of sodium hydroxide = 40 gm of sodium hydroxide. so we can say;

If want to prepare 1 molar NaOH solution then we need 40 gm NaOH to dissolve in one liter of water so it became one 1 molar NaOH solution.
