Mass is the quantity of matter present; weight is a measure of the pull of gravity on matter and is measured in pounds or Newtons. However, it is common usage in chemistry to talk about the “gram formula weight” or “atomic weight”rather than the technically correct term “gram formula mass” or “molar mass.”

The ratio of the mass of an object to it’s volume is known as DENSITY. Density = Mass/Volume. D = m/V. Two common density units (used in Chemistry) are g/mL and g/cm3. Temperature - the degree of hotness or coldness. Fahrenheit (˚F) Celsius (˚C) Kelvin (K) K = ˚C + 273 C = K - 273
