How much glucose would be needed to make 100 ml of a 0.1M solution? [M. Mass of glucose = 180 g] Answer: It would take 18 g in a liter to make a 0.1M solution. But, a volume of 100 ml would only require 1/10 th of 18, or 1.8 g.
The molecular mass of glucose (C 6 H 12 O 6 ) is 180 g. To make a 0.5 M solution of glucose, you should do which of the following?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
