Advanced Study Assignment: The Densities of Solids and Liquids

I weighed a flask and stopper on an analytical balance and found the total mass to be 31.601 g. The I filled the flask with water and obtained a mass for the fullstoppered flask of 60.735g. From these data, and the fact that at the temperature of the laboratory the density of water was 0.9973g/cm cubed. What is the volumeof the stoppered flask?

Mass of filled stoppered flask=mass of empty stoppered flask+mass of water, so mass of water=mass of filled flask-mass of empty flask.

Answer #1
Mass of stoppered flask = 31.601 g
Mass of water + Mass of stoppered flask = 60.735 g

From this, we can determined the mass of the water:
Mass of water = 60.735 g - 31.601 g = 29.134 g

The density of water is 0.9973 g/cm^3.

To determine the volume, we can use the following formula:
Volume = Mass / Density
Volume = 29.134 g / (0.9973 g/cm^3) = 29.21 cm^3 = 29.21 mL

The volume of the stoppered flask is 29.21 mL.

    Could someone assist me with this question? In the 19th century, J. B. A. Dumas devised a method for finding the molar mass of a volatile liquid from the volume, temperature, pressure, and mass of its vapor. (next column). He placed a sample of such a liquid in a flask that was closed with a stopper fitted with a narrow tube, immersed the flask in a hot water bath to vaporize the liquid, and then cooled the flask. Find the molar mass...
