Find the concentration of the final solution

[CrazCo]

500 millilitres of acetic acid is in solution and is then diluted yielding a 5 percent solution. What is the volume of said solution. (Note Concentration of acetic acid is 17.4 mol/l).

 

V1C1 = C2V2

 

500ml x 17.4 mol/l = 0.05 g/ml x V2

 

This is what I have for an equation but I think I took a step in the wrong direction. Help?

Strictly, there isn't enough nformation to answer the question. Do they want 5% by volume or 5% by mass?

If they want 5% by volume it's easy- 5% is 1 in 20 so you start with half a litre and end up with 20 times that much i.e. 10 Litres.

If the want 5% by mass then you need to know the mass of 500ml of acetic acid. They tell you the number of moles per litre, if you know what a mole wieghs you can do the rest of the arithmetic easily.
