The atomic masses of the elements Ca, C and O are 40, 12 and 16 respectively. Accordingly, the formula mass of calcium carbonate, CaCO3 should be 40 + 12 + 3(16) = 100.
1. Calculate formula massCalcium carbonate has chemical formula CaCO3.Its formula mass is 40.1 + 12.0 + 3(16.0) = 100.12. Apply formula to calculate number of moles of CaCO3Amount of CaCO3= mass/formula mass= 50/100.1= 0.50mol
Calcium ion is Ca2+ and the carbonate ion is CO32-
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.
The formula for it is CaCO3 Therefore it is fairly simple to work out. Ca is 40 C is 12 O is 16 x3 48 Add them all up 100 hope this helps :)
Well, darling, to find the number of formula units in 200 grams of Calcium Carbonate, you first need to calculate the molar mass of CaCO3. Once you do the math, you'll find that one mole of CaCO3 weighs 100.09 grams. So, 200 grams of CaCO3 represents 2 moles of the compound, which is equivalent to 2 times Avogadro's number (6.022 x 10^23) formula units. Voilà!
To find the number of moles in 73.4 kg of CaCO3, we first need to calculate the molar mass of CaCO3. The molar mass of CaCO3 is 100.09 g/mol. Converting 73.4 kg to grams gives 73,400 g. Dividing 73,400 g by the molar mass of CaCO3 gives approximately 733 moles.
Molar mass of CaCO3 = 100.0869 g/mol

CaCO3 is the chemical formula for calcium carbonate.
It is CaCO3.....it is the same as marbleFormula: CaCO3
Formula: CaCO3
The chemical formula of calcium carbonate is CaCO3.
Calcium ion is Ca2+ and the carbonate ion is CO32-
Molar mass of CaCO3 = 66.1221g CaCO3/mole CaCO3. This means that 1 mole CaCO3 = 66.1221g CaCO3. To find the mass of 4.5 mole CaCO3, complete the following calculation: 4.5g CaCO3 X 1mol CaCO3/66.1221g CaCO3 = 0.068 mole CaCO3.
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.
The chemical formula of aragonite is CaCO3.
250 grams CaCO3 (1 mole CaCO3/100.09 grams) = 2.50 moles of calcium carbonate
