Astudent obtained a clean dry glass-stoppered flask. she weighed the flask and stopper on an analytical balance and found the total mass to be 31.601 g. she then filled the flask with water and obtained a mass for the full stoppered flask of 60.735 g. from these data, and the fact that at the temperature of the used water its density is 0.9973 g/cm3 , find the volume of the stoppered flask
