A student added 1. 0 ml of liquid isopropanol (molar mass 60. 1 g/mol, density 0. 786 g/ml) to the dry 50-ml erlenmeyer flask (same flask used in question 1), placed a rubber stopper on it, and allowed it to evaporate--so the gas filled the container. The temperature of the lab was 21. 4oc. What is the temperature of the gas in kelvin?.
