I had a quiz today, and had no idea what the instructor expected us to do based off the information given. I'm trying to figure out how we were supposed to get the mass, volume, or moles to help solve the problems.
I don't want any answers, just advice on how to use the information to get me to the answers.
The information given:
Glucose in a sucrose solution with 2.3 m and a density of 1.12 g/mL.
She provided the molar mass for glucose. (180.18 g/mole)
The information required:
Mass of solution, solute, solvent
Moles of solute, solvent
Volume of solution, solute, solvent
I have absolutely no clue as to how we are supposed to get all that. I assumed the solvent is water, so I can determine the density of glucose in the solution. She didn't provide us any volume, mass, or moles.
Does anyone have any tips for this? I'm not the only student who didn't know what to do for this. I know it's got to be something really obvious, she was already grading quizzes when we turned them in so nothing was left out.
