Question

-) Define term 'malarity' calculat the molarity of
NaOH in the solution prepare by dissolving in 49
in enough
water to form
250 ml of solution.​

Answer 1

Answer:

Defination of Molarity: In a certain 1L solution, how many moles are dissolved is called 'molarity'.

Molarity of mentioned solution is 4.9 M (Molar)

Explanation:

Here,

number of mole, n = (49/40) mole

volume of the solution, V = 250mL = 0.25 L

Molarity of the solution,

S = n/V = (49/40) ÷ 0.25 = 4.9 M (Molar)

You have got you answer. :)
