Asample consisting of n mol of an ideal gas undergoes a reversible isobaric expansion from volume vi to volume 3vi. find the change in entropy of the gas by calculating, ∫dq / t, where dq = ncpdt. (use the following as necessary: cp and n.)

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.
