Which radioisotope has the fastest rate of decay?
(1) 14C (2) 53Fe (3) 220Fr (4) 42K

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

ok whats the question if not i cannot you i need question and need a thing to answer

50.23 i believe is correct but don't quote me on that.
