Homework Help: chemistry

Posted by solution chemistry on Monday, February 10, 2014 at 11:16pm.

In an experiment, ethanol standards and an n-propanol standard were to be prepared in water. The ethanol standards were weight% and the n-propanol could be either v/v or weight%. One of the questions for the report asks why it was ok to make the n-propanol a v/v%.

I overheard someone mention that it's because the density of ethanol is less than that of water but I'm unsure how that applies to how the solutions are made.
