Chemistry Concentration and Dilution Notes

Source: Haywood’s Concentration Slideshow

Concentration:

m=C×Vm=C×V

Variable Definition

M is mass

C is concentration (g/L)

V is volume (L).

Moles Calculation:

moles=mass (g)molar mass (g/mol)moles=molar mass (g/mol)mass (g)​

% Composition (by volume):

% Composition = volume of solute / total volume ×

PPM Calculation:

ppm=amount solute (g)amount solution (g)×106ppm=amount solution (g)amount solute (g)​

×10^6

Molarity:

M=moles of solutevolume of solution (L)M=volume of solution (L)moles of solute​

Dilution Formula:

C1V1=C2V2
