Answer to Question #22246 in Inorganic Chemistry for Abiodun

Question

Asolution in a bottle is 1.2 molar concentrated. What volume of it must be diluted with water to obtain
600cm3
of 0.05 molar solution.

Answer 1

For answering this question you need tocalculate amount of mol in final mixture.

0.05 mol per 1000 cm^3
x mol per 600cm^3

x = 0.03 mol

Now you need to calculate volume of solution in a bottle which
include amount of 0.03 mol

1.2 mol in 1000 cm^3
0.03 mol in V

V=25 cm^3 or 25 ml
