Solution chemistry
« on: May 04, 2021, 04:58:00 PM »
At room temp the solubility of glucose in water is 95grams of glucose per 100ML of water. If prepared solution is 170ML glucose in 179ml of water how would classify the solution?

Hi Moida,

For the NaCl question, you might start by writing out the info you are given in something like a factor label method type format. See if you can cancel units that would leave you with just the units (moles in this case) that you are looking for.

170 mL of glucose does not make much sense.  Could this be 170 grams?

It's not impossible that it was given in mL as long as you know the density, although I suspect you're right.
