-_-_ -1;er 4.1. LLUCUCU. Start each calculation by writing the values substituted for each variable. _.......=. I ..... 0005 . (blue beam m) =W (5000 g) Check your result as follows: . Oxygen-16 has 8 protons and 8 neutrons. Oxygen18 has 8 protons and 10 neutrons. The mass Of a proton is 1.6726x10-27 kg. The mass of a neutron is 1.6749x10-27 kg. Calculate the mass of Oxygen16 and Oxygen 18 using this information: Mass of Oxygen-16 = ( )x(1.6726x10-27 kg]+( ]x(l.6749x10n27 kg) = __ x 10-25 kg Mass of Oxygen18 = ( )x(1.6726x10-27 kg)+( )i(1.6749x10-27 kg] = __ x 10"26 kg Your results will not match exactly the results from the mass spectrorneter. This 11s because in the world of the nucleus, mass can turn into energy that binds the nuc eus together
