Question

solution is prepared by dissolving 2 gram of naoh solution 250 ml In A volumetric flask find molarity also football fan see AK LOOKING FOR MANAGER channel after 20/6/19

Answer 1

Answer:

M=0.2

Explanation:

we need to find out how many moles dissolved in 1000 ml of solution

NAOH=23+16+1

=40

1mole =40gm

2gm=2/40 mole

250ml has 2/40 mole

1000ml would have (2/40)×4 mole ..which is 0.2

so the molarity will be 0.2
