Final answer:
The question relates to Chemistry and concerns the absorption properties of acetone with respect to acetylene gas. Acetone, a solvent, can absorb acetylene, facilitating its use in industrial applications like welding. The exact number of times acetone can absorb its weight in acetylene is not explicitly given in the reference material.
Step-by-step explanation:
The student's question about acetone's ability to absorb acetylene pertains to physical properties of chemicals, which is a topic under Chemistry. Specifically, the fact that acetone can absorb many times its own weight in acetylene makes this a question about the physical interaction between two compounds.
Acetone, a solvent with the formula C3H6O, can absorb a significant amount of acetylene gas, C2H2, due to its chemical structure. Acetylene is a gas used in welding torches, and its storage and transportation can be facilitated by dissolving it in a liquid solvent like acetone. This property is utilized in acetylene tanks for safe storage and transport.
While the specific numerical answer to the student's multiple choice question is not provided in the reference information, this type of question generally tests a student's knowledge of material properties and their applications in real-world situations, such as in the storage of gases for industrial use.
