Question

An ice freezer behind a restaurant has a freon leak, releasing 33.03g of  C2H2F3Cl into the air every week. If the leak is not fixed, how many kilograms of fluorine will be released into the air over 6 months?  Assume there are 4 weeks in a month.

Answer 1

molar mass C₂H₂F₃Cl = 118.5 g/mol

Using dimensional analysis, we can solve as follows:

33.30g C₂H₂F₃Cl x 1 mol C₂H₂F₃Cl / 118.5 g = 0.2810 moles / week

0.2810 moles C₂H₂F₃Cl / week x 4 week/month x 6 months x 3 mol F/ mol C₂H₂F₃Cl x 19 g F /mol x 1 kg/1000 g = 0.3844 kg of F
