What is the liquid specific gravity of propane?

• A. 0.4
• B. 0.5
• C. 0.7
• D. 0.6

Answer: (B)

Liquid specific gravity compares how dense a liquid is to water. Propane in its liquid form is less dense than water, about half as dense, so its liquid specific gravity is around 0.5. Among common options, 0.5 is the best match because it reflects propane’s typical liquid density at standard conditions. The other values (0.4, 0.6, 0.7) would imply densities noticeably different from propane’s known liquid density.
