Concentration Measurements
Example 1:
Phosphoric acid is a weak acid with the chemical formula H3PO4. It is normally encountered as a colourless syrup of 85% concentration in water with the density of 1.88 g/mL at 25 °C. Calculate:
-
(a) the molarity of H3PO4.
-
(b) the molality of H3PO4.
-
(c) the mole fraction of H3PO4.
