1. if liquids droplets were left condensed on the inside flask walls, will the experimental molecular weight be higher, lower, or no different than the actual molecular weight? 2. if the flask is not dried prior to measuring the mass of the flask after it has been removed from the hot water bath will the experimental molecular weight be higher, lower, or no different, than the actual molecular weight? 3. if the no-hole rubber stopper is not placed firmly in the flask when the one-hole rubber stopped is replaced by the no-hole rubber stopper (so air enters the flask) will the experimental molecular weight be higher, lower, or no different than the true molecular weight? 4. if the mass of the gas is found by subtracting the mass of the flask plus the stopper and moist air from the mass of the flask plus stopper and unknown gas, will the experimental molecular weight be higher, lower, or no different than the true molecular weight?
