If a vitamins expiration date has passed It was supposed to contain 500 mg of Calcium but it has lost 325 mg of Calcium How many mg of Calcium is left?
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.

How many milligrams of calcium are present in 500 mg tablet of calcium carbonate?
The formula for calcium carbonate is CaCO3, and it has a gram formula mass of 100.09. The formula shows that each formula mass contains one calcium atom, which has a gram atomic mass of 40.08. Therefore, the mass fraction of calcium in calcium carbonate is 40.08/100.09, so that a 500 mg tablet of calcium carbonate contains 200 mg of calcium, to the justified number of significant digits.

How do you find out how many atoms are present in calcium?
To find out how many atoms are present in calcium, you would need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Simply divide the mass of the calcium sample by the atomic mass of calcium (40.08 g/mol) and then multiply by Avogadro's number to determine the number of atoms present.

A rolaid tablet contains calcium carbonate if 44.55 ml of 0.448 M hydrochloric acid is required to neutralize one tablet how many milligrams of calcium carbonate are in a rolaids tablet?
To calculate the amount of calcium carbonate in a Rolaids tablet, first determine the moles of hydrochloric acid used (moles = Molarity x Volume). Then, use the balanced chemical equation (1 mole of calcium carbonate reacts with 2 moles of hydrochloric acid) to find the moles of calcium carbonate. Finally, convert moles of calcium carbonate to milligrams using its molar mass.
