Question

What is the volume of 0.5M solution made by dissolving 102g of glycerol in water?

How do you work this out step by step? I know the answer is 2.2L

Thanks in advance

Hi Ruby! The work would look like this:

(102g) x (1 mol / 92.05g glycerol) x (1 L / 0.5 mol) = 2.2L

Basically you just need to set up a couple conversion factors to cancel out the grams and moles to get liters left. The work goes from grams to moles to liters. I checked my work on a calculator and got your answer as well of 2.2 L.

Hope this helps! Please feel free to reach out with any additional questions or help needed.
