Volume concentration

VOLUME CONCENTRATION (g/mL)

mL of solvent (water)	mL of solute (tobacco)	mL of solution	Solution Concentration (g/ml)
27	3	30	0,0033
24	6	30	0,0067
21	9	30	0,0100
17	13	30	0,0144
7	23	30	0,0256
0	30	30	0,0333

We firstly made a solution of 5g of tobacco with 150 mL of water, so the main concentration is

So if we do the rule of three we obtain the amount of tobacco. Applying the following method to all the measurements we will obtain the concentration of the amount of tobacco on each one.

  =     à x =  à x = 0,0256
