Which of the following possible sources of error might account for the discrepancy between your experimentally determined molecular weight and the theoretical value? Select all that apply: Hint: was your experimentally determined molecular weight greater than or less than the theoretical value? The person weighing the mass of the flask filled with water on the triple-beam balance forgot to put the foil on the flask when making this measurement: The COz gas collected did not completely displace all of the air from the flask: Some COz gas escaped from the flask prior to weighing: The desiccant in the drying tube was saturated and so some moisture entered the collection flask during the experiment: Too much hydrochloric acid was poured into the thistle tube during the experiment: The barometric pressure reading wasn't corrected for temperature and so the recorded value was greater than the actual pressure in the room. Some water got on the outside of the flask when measuring the mass of the flask filled with water (with foil) 0n the triple-beam balance
