Briefly answer the following question:
What is the fraction of the mass of water due to neutrons?
Mass of one mole (Avogadro Number) of neutrons ~ 1 g.
Mass of one neutron = 1 / Avogadro Number \(N_A\) x g.
Mass of one molecule of water = / \(N_A\) = 18 / \(N_A\) x g.
There are 8 neutrons in one atom of oxygen.
Mass of 8 neutrons = .
Fraction of mass of water due to neutrons ~ .
