So, the molar mass of H 2 O is (2 x 1.008) + 15.9994 = 18.0154 g/mol. How does molarity relate to concentration? Two solutions that have the same molarity will have the same number of molecules of the ...

The pH is a negative logarithmic scale, which measures the molar concentration of hydrogen ions from 1 to 10 14 ions. It therefore has no unit of measurement. Numbers on a negative logarithmic ...

Nanomolar (nM) is a unit of concentration commonly used in nanotechnology and related fields to express the number of particles, molecules, or other entities present in a given volume of solution. One ...

Example of molarity and concentration calculations. The scenario in which most lab scientists will encounter this type of calculation is when making up solutions following a standard operating ...
