would the molar mass of a volatile liquid be incorrectly high, incorrectly low or unaffected if
a)you did not completely vaporize the liquid when you heated it.
b)the foil cap got wet while you were cooling the flask and its contents with running water
c) you added the boiling stone to the flask after you had already determined the mass of the empty flask and foil cap.
d)you forgot to measure the volume of the flask, so you used the volume printed on the flask for your calculations
e) your unknown liquid had a boiling point of 102.3 degrees Celsius
I can't tell what you are doing.
