A sample of histamine having a mass of 385 mg is composed of 250 mg carbon, 31 mg of hydrogen, and 146 mg of nitrogen. The molar mass of histamine is 123 g/mol. What is the molecular formula for histamine?

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

yes it is balanced
