question

A technician is working with dry ice (solid CO_2) in a closed 6000 liter fume hood maintained at a constant pressure of 1.00atmand a constant temperature of 27°C. If he has not been conditioned to tolerate CO_2, he will succumb to CO_2 poisoning when the concen-tration rises to 10%, by volume, of the atmosphere. If the ventilation stops, what minimum weight of dry ice must sublimate to constitute a hazard? Assume that there was no CO_2 present initially.
