Question

what volume of water is to be added 200 cm cube of 0.5 molarity of any solution to make it 0.1 molarity of solution​

Answer 1

Answer:

Answe is 800 cm cube

Explanation:

M1 = 0.5

V1 = 200

M2 = 0.1

V2 = V

using M1V1 = M2V2

0.5 × 200 = 0.1 × V

SO, V = 1000 Cm cube

volume of water to be added,

= 1000 - 200

= 800 cm cube
