You have a container with gaseous hcn in your lab. its volume is 5 l and the temperature is 298 k. in the evening when you left your lab the pressure was 1.0 atm and the next morning it was 0.9 atm. first calculate how many moles of gas have escaped from the container. suppose that the lethal dose of hcn is 0.0001 g/m3 (i made this up) and the dimensions of the lab are 5 m latex: \times×4 m latex: \times×5 m. assuming that no hcn escaped from the lab, would the amount of hcn in the lab be sufficient to kill you when you entered the lab next morning? group of answer choices
