As the volume of a fixed mass of a gas increases at constant temperature, the pressure of the gas A) increases
B) decreases
C) remains the same

Remain the same not sure about the answer

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.
