A vitamin's expiration date has passed. It was suppose to contain 500 mg of Calcium, but it has lost 325 mg of Calcium. How many mg of Calcium is left? Is this a trick question? Calcium is not a vitamin, but an element. Calcium, being an element, can't be 'lost', since, according to the laws of conservation, matter cannot be created nor destroyed (except in nuclear reactions). Nor can calcium be converted to something else, merely reacted with to form some other calcium compound, thus is still there. Radioactive isotopes of Calcium could decay over long periods, so it also depends on how long the expiry date has passed, and what isotopes are involved. If you somehow meant to type vitamin C instead of Calcium, then the matter is simple arithmetic and doesn't need to be answered on this forum, I would think.
