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 mass measurement on the display is the mass of the sample only. The subtraction method involves measuring the mass of a sample by calculating the difference in the mass of a container with and without the added sample. The balance should be set to zero before the empty container is added to get accurate results with the subtraction method.
