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 ...

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 ...
