Question

Calculate the no of electronic proton and neutron in 1 mol of o

Answer 1

1 mole of O contains 6.022*10^23 atoms of oxygen. One O atom contains 8 electrons and same number of protons. Then the number of protons =8*6.022*10^23
=48.176*10^23
=4.8176*10^24
no.of neutrons per atom = mass no. - no.of protons per atom
= 16-8
=8
no.of atoms = 6.022*10^23
no.of neutrons =8*6.022*10^23
=4.8176*10^24
therefore,
number of protons =number of neutrons
=4.8176*10^24.
