Several tablespoons of Vitamin C are placed in an empty bottle containing only air. The botle is then securely closed with an air-tight lid or cap. If the air contains 18.9 % oxygen by volume and the volume of the air in the bottle is 2.5 litres, how much Vitamin C will be consumed? Express your answer to the nearest milligram of Vitamin C (no decimal places and no decimal point) and do not include any units in your resonse. Note: The actual amount of Vitamin C placed in the bottle at the start is not important here. It just shows that there is an excess of Vitamin C present. The volume of the Vitamin C has no effect on the volume of the air in the bottle. We will also assume that the reaction proceeds until all the oxygen in the air is consumed.
