2 litres of acetronitrile is accidently spilt in a school lab of dimensions 40x20x10m and most evaporates calculate the ambient concentration of acetonitrile reach assuming that there are no air changes in the lab

I looked up the density of acetonitrile on the Internet and found 720 kg/m^3. Use that to convert 2 L to grams (or kg). Then calculate the volume of the room from the dimensions. concn in the room = kg gas/m^3 or the room.
