How do you convert sucrose vs water ratio into concentration percentage?
« on: September 29, 2012, 09:53:34 PM »
How would you convert the below solutions into concentration percentages?

90ml 100% sucrose
45ml/45ml sucrose and h2o
30ml sucrose 60ml h2o
18ml sucrose 72ml h2o
9ml sucrose 81ml h2o
4.5ml sucrose 85.5ml h2o
3.6ml sucrose 86.4ml h2o

Please elaborate - what you are given, what you are expected to get.

While the answer is not necessarily difficult, this type of question is usually a product of a confusion over how the solutions are prepared and what the concentration really is.

Can you start by defining percentage for us?  It doesn't have to be solution percentage, the simple definition of "per cent" will help you start to understand what you're expected to do, with these problems.
