I have a 1% w DMG solution. Now in an analysis I need to use 0.178g DMG. How can I calculate what volume of solution contains that much of DMG? Density of the alcohol is 0.79 g/ml. Is it possible to calculate the vol of the solution from here?

1% w DMG means that you have 1 g of DMG for eacht 100 g of solution. So I suggest you do this:

1/0.178 = x
100/x = the volume you need for 0.178 g DMG
