Hemolytic uremic syndrome. This rare disorder causes a sharp drop in platelets, destruction of red blood cells and impairment of kidney function. Sometimes it can occur in association with a bacterial Escherichia coli (E. coli) infection, such as may be acquired from eating raw or undercooked meat.
Atomic mass is measured in atomic mass units, or amu. Atomic mass units were taken from one proton or neutron of carbon-12, which each weigh 1 amu. Carbon-12 weighs exactly 12 amu. On the periodic table , you can see that carbon (C) has a number underneath it that is very close to 12. This is called the atomic mass.
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred to as atomic weight, but the term mass is more accurate.)
