Asample of oxygen gas occupies 3.60 liters at a pressure of 1.00 atm. if temperature is held constant, what will be the volume of the oxygen gas at a pressure of 2.50 atm?

0.694 l

1.44 l

4.35 l

9.20 l

P1V1=P2V2
(1.00atm)(3.60L)=(2.50atm)V
3.60=(2.50atm)V
3.60/2.50=V
1.44L=V

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.
