When 31. 9 mg of a compound containing only carbon and hydrogen is burned completely in oxygen, it yields 87. 7 mg of carbon dioxide and 71. 8 mg of water. How much oxygen is used up?.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Anions are negative charged ions
