Answer: The new molarity is 2.4 M
Explanation:
According to the dilution law,
[tex]C_1V_1=C_2V_2[/tex]
where,
[tex]C_1[/tex] = concentration of pure solution = 3 M
[tex]V_1[/tex] = volume of pure solution = 200 ml
[tex]C_2[/tex] = concentration of diluted solution= ?
[tex]V_2[/tex] = volume of diluted solution= 250 ml
Putting in the values:
[tex]3M\times 200ml=M_2\times 250ml[/tex]
[tex]M_2=2.4M[/tex]
Thus the new molarity is 2.4 M
