Question

A cylindrical tube of length 27.75 cm and radius 2.00 cm is filled with argon gas. The empty tube weighs 188.25 g. The tube filled with argon weighs 188.87 g. Calculate the density.

formula =


`V = \pi r^2h`

Answer 1

Explanation:

V= π(2)^2(27.75)

= 348.72cm^3

D=188.87g/348.72cm^3

= 0.54g/cm^3
