Question

Molarity of 20ml of \sf {H_{2}SO&{4}} that can exactly neutralise 5ml of 1M NaOH is ?​

Answer 1

Explanation:

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.
