You can put this solution on YOUR website! In words:
(final liters of glucose)/(final toal liters of broth) = final percent glucose
I'm told that the final percent glucose is 50.1%
How much glucose is in the 16.1 liters of 57% broth? liters
I'm not told how much 40.2% broth I have, so I'll call the
liters of this broth
There is glucose in this broth
mulltiply both sides by liters
The amount of 50.1% broth is liters answer
Check my math, but I think the method is good
