What volume of WATER MUST BE ADDED to 10.0 mL of 6.0 M NaOH to make a solution that is 0.30 M in NaOH? Assume that the volumes are additive.
a. 10 mL
b. 190 mL
c. 200 mL
d. 210 mL
e. 500 mL

    you are diluting it 20 times? Add 1 part original, 19 parts water.



    Now if you want to do it the hard way:


    molesacid=10ml*6M=V*.3

    Volumetotal=200ml
    so water added =200-10ml
