Asample of a compound contains 30.0 g c and 5.05 g h. its molar mass is 78.12 g/mol. what is the compound’s molecular formula? ch c2h2 c6h6 c6h

The correct answer would be the third option. C6H6 most likely is the sample of compound since its molar mass sums up to 78.12 grams per mole as compared to other choices. CH has only a molar mass of 13.02 grams per mole, C2H2 has a molar mass of 26.04 and C6H has a molar mass of 73.07 grams per mole.

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.
