Final answer:
Acetone can typically absorb around 20 to 25 times its own volume in acetylene, a property due to its molecular structure with a significant dipole moment and higher boiling point.
Step-by-step explanation:
The question pertains to the absorption capacity of acetone for acetylene gas. While the exact number was not provided in the information given, it's important to note that acetone is commonly used for acetylene storage due to its ability to absorb large volumes of acetylene.
This is attributed to acetone's structure, which includes a polar C=O double bond and two nonpolar methyl groups, leading to a significant dipole moment and a higher boiling point. Therefore, acetone’s molecular structure allows it to dissolve or absorb acetylene effectively. In industrial practice, acetone can absorb approximately 20 to 25 times its own volume in acetylene under pressure. This information highlights the importance of understanding the chemical properties and interactions between substances like acetylene and acetone.
