Answer: 0.15M
Explanation:
The expression used will be :
[tex]M_1V_1=M_2V_2[/tex]
where,
[tex]M_1[/tex] = concentration of stock solution = 0.30 M
[tex]M_2[/tex] = concentration of dilute solution = ?
[tex]V_1[/tex] = volume of stock solution = 25 ml
[tex]V_2[/tex] = volume of dilute solution= 50 ml
Now put all the given values in the above law, we get :
[tex](0.30M\times 25ml=(M_2\times 50ml)[/tex]
By solving the terms, we get :
[tex]M_2=0.15M[/tex]
Therefore, the concentration of new solution will be 0.15 M.
