Question

IF 500 ml of a 5M solution is diluted in 1500 ml what will be the molarity of the solution obtained?

Answer 1

Answer:

Molarity of solution obtained =1.67 M

Explanation:

Given

Molarity of the 500ml solution, M1= 5M

Volume of solute 5M, V1 = 500ml

Diluted solution, V2=1500ml

Molarity = no. of moles/Volume of solute

5= no.of moles/500

no. of moles = 2500

Now for 1500ml of solute,

Moarity for 1500 ml solution = 2500/1500 = 1.67M

Answer 2

Given:

Molarity of the solution (M1) = 5 M

Volume of the Solution (V1) = 500 ml

Volume of the Solution (V2) = 1500 ml

To Find:

Molarity of solution 2

Formula used to find the answer:

M1V1 = M2V2

Substituting the values known to us in this formula we get:

(5) (500) = (1500) M2

2500 = 1500(M2)

M2 = 2500 / 1500

M2 = 1.66 M

Therefore, 1.66 is the molarity of the solution obtained if 500 ml of a 5 M solution is diluted in 1500 ml.
