[SOLVED] Percent of solution 1. The problem statement, all variables and given/known data Let's say we have 5% glucose of a 10 mL solution. So that would imply that .5 mL of the solution is glucose, but that does not really tell me how much glucose. Is it assumed that the glucose is 1 molar? I ask because in one of my bio labs we did a lab where we were given exactly as stated above. Knowing the exact amount of glucose was not needed for the lab, however, I would like to understand this for future use. Thanks for any input.
