Inorganic Chemistry
Sulfur dioxide (SO2
), a gas that plays a central role in the formation of acid rain, is found in the exhaust of
automobiles and power plants. Consider a 1.53-L sample of gaseous SO2 at a pressure of 5.6x103 Pa. If the
pressure is changed to 1.5x104 Pa at a constant temperature, what will be the new volume of the gas?

Diosmetin is a natural flavonoid present in the rind of ‘kalamansi’ and the leaves of ‘alagao’. It is a good antioxidant and anti-inflammatory agent. It is medically prescribed to treat hemorrhoids and varicose veins. Its molecular weight is 300.26 g/mol.
(a) How many millimoles (mmol) of diosmetin are in a caplet that contains 250 mg of diosmetin?
(b) If one is prescribed to take 3 caplets a day, how many milligrams of diosmetin are to be taken a day?
(c) If one has to obtain 1.5 mole of diosmetin for treatment, how many caplets does he need?
