A photocopier begins a large printing job. The copier emits ozone as it prints at a rate of $3000$g$/$h$.$ The copier is in a room that measures $3$ m $\backslash$times $2\mathrm{.}5$ m $\backslash$times $3\mathrm{.}4$ m and is ventilated at a rate of$1$ turnover per hour. Ozone decomposes in air with a half$-$life of $3$ days at room temperature.The Occupational Safety and Health Administration $($OSHA$)$ sets an exposure limit to ozoneof $200$g$/$m$3.$ If the print job took $40$ minutes to complete, by the end of that time was theOSHA limit exceeded in the copier room?

Write a mass balance with explicit terms specific to this problem $($not the general startingpoint$).$ You can then use formulas to answer the question. Assume that the air initiallycontained no ozone and the exterior air also contained no ozone.
