What are your variables in the following problem: If 0.950 mol of O2 has a volume of 20.0 L at some temperature and pressure, what would be the volume of 1.350 mol of O2?

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest
