A student obtanied 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 fpr the full stoppered flask of 60.735 g. From these data, and the fact that at the temperature of the laboratory the density of water was 0.9973 g/cm3, find the volume of the stoppered flask.
Mass of water=______________g-________g=_________g

mass of water = (60.735 g - 31.601 g)
Volume of water = (60.735 g - 31.601 g) / (0.9973 g/cm3)
You will get the answer in cm3 i.e. volume.

just so you know cm3 is equal to mL.
density= (mass)/ volume, so 0.9973g/ml= (60.735g-31.601g)/ (volume), which is the unknown. Easy to calculate.

Hey dude,
That's just pure laziness on your part...Just follow the units...The answer is 29.21 cm3
