solution chemistry

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-propano...

How would you prepare a solution of about 8mg/100ml of ascorbic acid in water (25ml)?

How would you prepare a solution of about 8mg/100ml of ascorbic acid in water (25ml)? I'm not sure if they mean to use that ratio of ascorbic acid in water to make a 25 ml solution or if the wording means something else.

the ethanol standards made were mixed with the n-propanol and ran through a gas chromatograph in order to plot calibration curves using both peak area and peak height data obtained from the chromatograms. the goal of the lab was to determine the %ethanol...

Ah I see, so because the same n-propanol solution was used for all the standards, the concentration remained constant regardless of what it was. And since the ethanol standards were used for the calibration curve they need to be more exact?

Thanks for you help.

I'm not sure if they mean to use that ratio but in a 25 ml solution.
