Occupational safety and health administration has set the limit on the maximum percentage of carbon dioxide (co2) in air a worker can breathe at 0.500% by mole. if dry ice (solid co2) is sublimating (becoming a gas) in a room at a rate of 0.880 mol/min, what is the minimum rate that fresh air has to be supplied to the room so that the concentration of co2 in the room doesn't exceed 0.500% by mole? assume the room is well mixed, and the volume of the solid dry ice does not change
