Copper (II) oxide is a fine powder that can be easily inhaled if suspended as a dust in the air. The work exposure limit for workers is 0.2 mg/m^3. Using the dimensions of our classroom (11.57m x 8.7m x 2.61m), how many grams of copper (II) oxide would need to be dispersed to have this concentration of copper (II) oxide in the air throughout the lab. Show all work!
Find the volumn of the classroom from the given dimensions in cubic meters.
The product of this volumn and the 8 hour exposure limit gives the total acceptable air inventory of the lab in mg.
