If the number of moles in a balloon is doubled, but the temperature and pressure don't change, what happens to the volume? a
It increases, but not in proportion with the moles
b
It is cut in half
c
It doubles
d
It does not chang

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
