The specific gravity of propane liquid is equal to which value?

Explanation:
Specific gravity compares a liquid’s density to water’s density; water is 1.00 g/mL, so the SG is essentially the density in g/mL. Liquid propane has a density around 0.51 g/mL, meaning its SG is about 0.51. That places propane liquid well below water in density, so its SG is less than 1.00. Values like 0.60, 0.75, or 1.00 would imply a denser liquid or no density advantage over water, which doesn’t match propane’s actual density.
