To measure concentration, you compare the amount of the solute to the total amount of the solution.
Altimeter.
Diffusion is movement of molecules, from region of higher concentration, to the region of lower concentration, along concentration gradient.
Substances of a higher concentration (or with higher level of water molecules) are more soluble than lower concentration liquids.
it is called a measureing tape

This is called diffusion. Substances move randomly, from an area of high concentration to an area of low concentration. Osmosis is a specific type of diffusion that only involves the random movement of water.
Using Pythagoras' theorem it works out as 15 inches
osmosis moves through a membrane diffusion moves from higher concentration to lower concentration
The rate of diffusion tapers off with higher amounts of glucose due to the principle of concentration gradient. As the concentration of glucose increases, the gradient between areas of high and low concentration decreases, resulting in slower diffusion rates. This is because diffusion is driven by the movement of molecules from areas of high concentration to areas of low concentration, and as the concentration levels equalize, the rate of diffusion decreases.
you can use tape measures such as rulers
