Question

Popeye wants to make a dilute spinach solution for Sweetpea's bottle. How much 3.0 M spinach solution should he add to the 500.0 mL bottle if he wants the final solution to be 0.30 M?

Answer 1

Answer : The volume of 3.0 M spinach solution added should be, 50 mL

Explanation :

Formula used :

`M_1V_1=M_2V_2`

where,

`M_1\text{ and }V_1` are the initial molarity and volume of spinach solution.

`M_2\text{ and }V_2` are the final molarity and volume of diluted spinach solution.

We are given:

`M_1=3.0M\\V_1=?\\M_2=0.30M\\V_2=500.0mL`

Now put all the given values in above equation, we get:

`3.0M* V_1=0.30M* 500.0mL\\\\V_1=50mL`

Hence, the volume of 3.0 M spinach solution added should be, 50 mL
