Question

A 6.00 ft cylinder has a radius of 26 in. It contains 189 lb of helium at 25 celsius. Express the volume of the cylinder (V=ðr²h) in liters, the amount of helium in moles and the temperature in Kelvin.

Answer 1

Convert 6 ft to cm, 26 inches to cm and 189 lb to grams.
V = pi*h*r^2
Kelvin = 273 + C.
mols = grams/molar mass
