WebThe element oxygen consists of three isotopes with masses 15.994915, 16.999133, and 17.99916. The relative abundances of these three isotopes are 99.7587, 0.0374, and 0.2039, respectively. From these data calculate the average atomic mass of oxygen.
How to Calculate Average Atomic Mass Chemistry
WebCarbon-12 has a mass of 12 amu by definition. Theoretically, this would mean that each proton and each neutron has a mass of one amu, but this turns out not to be so. The actual mass of a proton is about 1.007 amu, and the mass of a neutron is about 1.008 amu. If you add the masses of six protons and six neutrons, you get 12.09. WebHow to Calculate Average Atomic Mass: Example 1. Calculate the average atomic mass of boron given that 19.8% of its naturally occurring atoms have a mass of 10.013 amu … greyhound burton on the wolds menu
