o If given an amount of something in grams, use the molar weight to convert to moles. Remember that molar weight is given in grams/mole so you would need to divide the mass by the molar mass to get moles. o If given an amount in liters, you should also be given either a concentration in g/L or molarity in mol/L.

convert to the units of ppm by multiplying 24.45 x 10 mg/m3 ÷ 78 = 3.13 ppm. Note: Sometimes you will see chemical concentrations in air given in concentration per cubic feet (ft3) instead of concentration per cubic meter (m3). The conversion from cubic feet to cubic meter and vice versa is as follows: 1 ft3 = 0.02832 m3 and 1 m3 = 35.31 ft3.
