3.5 moles CaCO3 (1 mole carbon/1 mole CaCO3)
= 3.5 moles
The formula given shows that each formula unit or mole contains one calcium atom; therefore, 2.5 moles of calcium chloride contains 2.5 moles of calcium atoms.
To determine the grams of calcium carbonate needed, we first calculate the moles of carbon dioxide using the ideal gas law. At STP, 1 mole of any ideal gas occupies 22.4 L. Therefore, 49.0 L of carbon dioxide is 49.0/22.4 moles. From the balanced chemical equation, we know that 1 mole of calcium carbonate produces 1 mole of carbon dioxide. Finally, using the molar mass of calcium carbonate, we can convert moles to grams.
Assuming each Tums tablet contains 500 mg of calcium carbonate, there is a total of 6 grams of calcium carbonate in one roll of Tums (12 tablets x 500 mg). To calculate the number of moles, divide the mass by the molar mass of calcium carbonate (100.09 g/mol), yielding around 0.06 moles of calcium carbonate in one roll of Tums.
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
A mole of H2 molecules contains 6.023 x 10^(23) H2 molecules or 2 moles of H atoms (since each molecules has 2 atoms). A mole of CaCO3 (calcium carbonate) has one mole (Avogadro number) of Ca atoms, one mole of C atoms and 3 moles of O atoms.
The number of moles of calcium carbonate are 3.5 moles. , there are 1 mole of calcium (Ca) atom, 1 mole of carbon (C) atom and 3 moles of oxygen (O) atoms.
1 mole of calcium carbonate produces 1 mole of carbon dioxide when it decomposes. Therefore, if 2.5 moles of calcium carbonate is consumed, 2.5 moles of carbon dioxide will be produced.
2,8 moles of calcium carbonate have 240,208 g.
Calcium carbonate contains 3 elements, calcium, carbon, and oxygen. The formula is CaCO3.
The formula given shows that each formula unit or mole contains one calcium atom; therefore, 2.5 moles of calcium chloride contains 2.5 moles of calcium atoms.

Finally, using the molar mass of calcium carbonate, we can convert moles to grams.
Calcium carbonate, CaCO3 has formula mass of 40.1+12.0+3(16.0) = 100.1Amount of CaCO3 = 1.719/100.1 = 0.0172molThere are 0.0172 moles of calcium carbonate in a 1.719 gram pure sample.
Calcium carbonate contains three elements: calcium, carbon, and oxygen.
Assuming each Tums tablet contains 500 mg of calcium carbonate, there is a total of 6 grams of calcium carbonate in one roll of Tums (12 tablets x 500 mg). To calculate the number of moles, divide the mass by the molar mass of calcium carbonate (100.09 g/mol), yielding around 0.06 moles of calcium carbonate in one roll of Tums.
Calcium Carbonate (CaCO3)I mol CaCO3 contains 3 mol Oxygen atomsso 4.25 mol CaCO3 will have 12.75 mol Oxygen Atoms.
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
To find the number of moles in 8.23 x 10^24 molecules of calcium carbonate, you first need to determine the molar amount of molecules in one mole of calcium carbonate by using Avogadro's number. Then, divide the given number of molecules by the molar amount to calculate the number of moles.
