You are in a poorly ventilated laboratory (V = 3m x 8m x 4m). Contrary to laboratory rules, you drink water from an open water bottle in the laboratory, that has been left there, open, overnight (V = 1 L). A small vial containing 5 grams of cyclopentane (C₅H₁₀) had been left open in the lab overnight, outside the fume hood, and has evaporated. Assuming equilibrium conditions, what is the concentration of cyclopentane in the air that you breathe in mass/volume units (milligrams/m³) and parts per million (ppm). Assuming equilibrium, what is the concentration of cyclopentane in the water that you are drinking? Based on what we know about the toxicity of cyclopentane, is this a serious problem or not?
