Question

If I add water to 100mL of a 0.15 M NaOH solution until the final volume is 150mL, what will the molarity of the diluted solution be?

Answer 1

Answer: The molarity of the diluted solution be 0.10 M

Step-by-step explanation:

According to the dilution law,

`C_1V_1=C_2V_2`

where,

`C_1` = concentration of concentrated solution = 0.15 M

`V_1` = volume of concentrated solution = 100 ml

`C_2` = concentration of diluted solution= ?

`V_2` = volume of diluted solution= 150 ml

Putting the values we get:

`0.15* 100=M_2* 150`

`M_2=0.10M`

Thus the molarity of the diluted solution be 0.10 M
