A small storage tank for liquefied petroleum gas (LPG) appears to be spherical and have a diameter of about 1 ft.Suppose that some common volumes for LPG tanks are 1 gal, 2 gal,5 gal, and 10 gal. Which is the most probable voume of this particular tank?

DrBob222,
Volume = (4/3)*pi*r^3.
If you use 1/2 foot for radius, then the volume will be in cubic feet. Go to google, type in "xxxcubic feet to U.S. gallons" without the quotation marks (where xxx is the number of cubic feet you calculate), then hit enter. The answer in gallons should appear.

Pam,
What is the volume of 3.25 moles of a gas at a temperature of 115 K and a pressure of 275 kPa?
