Molarity Calculator | Technology Networks

For sodium chloride (NaCl) they are in a ratio of 1:1 so the molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol. For a compound like water (H 2 O), 1 mole of hydrogen (H) is 1.008 g/mol and 1 mole of oxygen (O) is 15.9994 g/mol. 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?
