Antacid tablets, such as tums, are mainly calcium carbonate. Calculate the mass of a tums tablet which contains 1000 mg of calcium.

Respuesta :

The formula for calcium carbonate is

CaCO3

So each mole of calcium carbonate contains one mole of calcium

Molar mass of calcium carbonate = 100g/mole

Atomic mass of calcium = 40g/ mole

Hence if 40g of calcium is present it means we have 100g of calcium carbonate

if 1 g of calcium is present it means we have 100/ 40 g of calcium carbonate

So if 1000 mg of calcium is present = 100 X 1000 / 40 mg of CaCO3 is present

                                                          = 2500 mg of CaCO3 in tum tablets
