I would say none of the above:ManzRDH said:How many ml of H20 must be added to 65 ml of a 5.5 m solution of NaOH in order to perpare a 1.2 M NaOH solution?
a- 230 ml
b- 235 ml
c- 229 ml
d- 1 L
This is right but I think there is one more step to the problem. The question asks how much water should be added. Since V2=298 ml and we already had 65 ml (v1), the volume of H20 that should be added is 298-65=233ml.dexadental said:m1v1=m2v2 is applied here.
What is v2? Do the math...
= .298 L which equals about 299 mL, I'm thinking its none of the above.
Just a quick look at this problem, don't have time to do the details...I think its right though.
