What is the correct mathematical relationship between the number of moles, the volume, and the standard molar volume of a substance?

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

let that person have a turn to speak : )
