Homework Statement

I have to dissolve phenylthiourea in a phosphate buffer solution. The final molarity of the phenylthiourea is 10^-5, but it says to dissolve it in ethanol. Does this mean that I have to dissolve my weight of phenylthiourea in a minimal amount of ethanol, then bring that to volume with the phosphate buffer?
