  • Density is the ratio of mass to volume

  • Molarity is the ratio of moles of solute to liters of solution

  • Molality is the ratio of moles of solute to mass of solvent

  • Percent abundance is the ratio of number of atoms of a given isotope to the total number of atoms of all isotopes of that element, multiplied by 100

  • Boyle’s law states that the pressure of a gas is inversely proportional to the volume of the gas

  • Charles’ law states that the pressure of a gas is directly proportional to the temperature of the gas

  • Guy-Lussac’s law states that the volume of a gas is directly proportional to the temperature of the gas
