Question

Porous materials soaked in acetone are placed in acetylene cylinders to create a lot of very small volumes, each with very little acetylene gas. Acetone is used because it dissolves _______ times its own volume of acetylene for every 14.7 psig pressure, effectively storing the acetylene as a liquid.

A) 2
B) 5
C) 10
D) 15

Answer 1

Acetone dissolves 25 times its volume of acetylene under 14.7 psig pressure, allowing for effective liquefication and storage of acetylene in cylinders.

Step-by-step explanation:

Porous materials soaked in acetone are used in acetylene cylinders to create very small volumes, with each volume containing a small amount of acetylene gas. Acetone (C3H6O) is utilized because it can dissolve a significant amount of acetylene; precisely, acetone dissolves 25 times its own volume of acetylene for every 14.7 psig (pounds per square inch gauge) pressure. Therefore, this property of acetone allows for efficient storage of acetylene by liquefying it under pressure. The correct answer for the amount of acetylene acetone can dissolve under the given conditions is thus 25 times its volume (Option C).
