If you burned 4.96 X 10^31molecules of ethane (C2H6), what mass of ethane did you burn?

The gas would begin to expand, and eventually the can would burst or explode.

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.

Ithink is a because if say increased in electronegativity
