A – solution stoichiometry. First multiply molarity by volume to get moles. Convert from moles to moles using molar ratio, then use molarity given and moles calculated to get the volume. Remember that molarity is equal to moles of solute / L of solution.

Number of moles = mass / molar mass (n = m/MM) Volumes of gases in chemical reactions. 1 mole of two gases weighed at the same temperature weigh the same. Relate stoichiometry to the law of conservation of mass in chemical reactions by investigating: Balancing chemical equations. Number of moles of each element must be equal on both sides

Common units for concentration measurements include mol/L, mmol/L, mg/L, mg/dL, and μg/mL. Others are also used. You need to be able to convert between these measurements readily. (Note that concentrations in mol/L are also called molar, and abbreviated M. A 2.5 mM solution, contains 2.5 mmol/L) Examples:

Matter, Measurement, The Atom and Stoichiometry
The units of molar mass are g/mol. The molar mass of a molecule is the sum of the molar masses of the atoms. Molar masses for elements are found on the periodic table. The formula weight is numerically equal to the molar mass. Interconverting Masses, Moles and Number of Particles. To convert between grams and moles, we use molar mass.
