Answer to Question #144651 in General Chemistry for MartinJay Zaballero

Question

One of the uses of titanium is on the structure of the bodies of planes since it is strong despite of being lightweight. Titanium has a density of 4.55 g/cm3. What is the diameter (in millimeters) of a cylinder of titanium that is 7.75 cm long with a mass of 0.153kg

Answer 1

p=m/V.

V=m/p.

V= hπr^2.

r=√(V/hπ)

d=2r.

V=153/4.55 = 33,6263736 cm3.

r=√(33,6263736/7.75 x 3.14)= 1,17550334 cm.

d= 1,17550334 x 2 = 2,35100668 cm.
