Different tissues/cells contain different solutes, need to do lots of testing to identify the correct concentration of each solute and have the correct combination in solution.

My hypothesis is that if the concentration of sugar changes the mass will decrease if the concentration of sugar increase, and that in pure water with high concentration the mass will increase.


I found an explanation on dilute…



I used these notes and got 19/20! Helpful, to get full marks I needed to work on method.
