Question #18112
what is the mass of one atom in a sample of 0.543 of oxygen (gas)
Expert's answer
Number of protons in oxygen atom: 8
Mass of one proton = 1.67262158 x 10-27 kg
Mass of protons in one oxygen atom = 1.338097264 x 10-26 kg
Mass of one neutron: 1.674927293 x 10-27 kg
Mass of neutrons in one oxygen atom: 1.33994183 x 10-26 (for 8 neutrons)
Mass of one oxygen atom: 2.67803909 x 10-26 (protons + neutrons).
