-Solutions are homogeneous mixtures composed of a solute and a solvent
-solute is the chemical present in the lesser amount (whatever is dissolved)
-solvent is the hemical present in the greater amount (whatever does the dissolving)
-Chemicals dissolved in water are aqueous
eg. NaCl (aq)
-Concentration can be expressed in many different ways (g/L, mL/L, % by volume, % by mass, mol/L)
-the most common way is mol/L which is also called Molarity
-mol/L = M
-[HCl] = concentration of HCl
Eg. Determine the concentration of 16.0 g of C6H12O6 in 0.750 L of water
16.0g x 1mol/180g x 1/.75L = .119 M
