M = moles of solute /L of soln.
moles of solute = M x V V = moles/M
m= moles of solute /kg of solvent
moles of solute = m x kg of solvent kg of solvent = moles/ m
grams of A to moles A to moles of B ( molar mass and molar ratio for stoichiometry problems)

M1 x V1 = M 2 x V2 for dilution problems


Chapter 4 section 4.5 concentration of solutions, concentration of ions in the solution, molarity, interconverting molarity, moles and volume, dilution, solution stoichiometry and chemical analysis, titrations, for this section you need to know to write formula equation from the word reactants and products, balance it before you solve the problem, you will be asked to find the grams of the product, moles, molarity and volume. Ch. 13, solvation, hydration, saturated, unsaturated and supersaturated solutions, factors affecting the solubility, solute-solvent interactions, polar and non-polar solvents, like dissolves like, polar liquids dissolve in polar solvents, non-polar liquids dissolve in non-polar solvents miscible and immiscible , effect of temperature and pressure on the solubility of solids, liquids and gases, mass percent, finding mole fraction, molality, molarity from the mass %.
