I'm sure that you cannot have the formation of Iron (iii) carbonate due to it's strong acidic nature, however when we have iron(iii)hexa-aqua ions and add some carbonate, which acts as a base, we form iron(II) carbonate. FeCO3. This is just what I have learnt feel free to challenge or correct me anyone.

To the nearest gram, molar mass of aluminium carbonate is 234 g/mol.
What is the percent mass of calcium in a calcium supplement if 1.35-g of calcium carbonate is extracted from a 2.36-g pill?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To calculate the percent mass of calcium, you need to divide the molar mass of calcium (40.08 g/mol) by the molar mass of calcium carbonate. This gives you a result of 0.4006, meaning that calcium constitutes approximately 40.06% of the mass of calcium carbonate.
What is the percent composition by mass of iron in iron (III) chloride?
To calculate the percent composition by mass of iron in iron (III) chloride (FeCl₃), first determine its molar mass. The molar mass of Fe is approximately 55.85 g/mol, and for Cl, it is about 35.45 g/mol, giving FeCl₃ a total molar mass of approximately 162.2 g/mol (55.85 + 3 × 35.45). The percent composition of iron is then calculated as (mass of Fe / molar mass of FeCl₃) × 100, which is (55.85 / 162.2) × 100 ≈ 34.4%. Thus, the percent composition by mass of iron in iron (III) chloride is approximately 34.4%.

What is the molar mass of compound Fe3 Po4 2?
The molar mass of the compound iron(III) phosphate, Fe₃(PO₄)₂, can be calculated by adding the molar masses of its constituent elements. Iron (Fe) has a molar mass of about 55.85 g/mol, phosphorus (P) about 30.97 g/mol, and oxygen (O) about 16.00 g/mol. Thus, the molar mass of Fe₃(PO₄)₂ is approximately 3(55.85) + 2(30.97) + 8(16.00) = 186.73 g/mol.

The formula for sodium carbonate is Na2CO3. Figure the molar mass of sodium carbonate to the nearest gram?
To calculate the molar mass of sodium carbonate (Na2CO3), you can add up the atomic masses of each element in the formula: 2(Na) + 1(C) + 3(O). The atomic masses are: Na = 23 g/mol, C = 12 g/mol, O = 16 g/mol. Therefore, the molar mass of sodium carbonate is approximately 106 grams/mol.
How many moles are in sodium carbonate?
To calculate the number of moles in sodium carbonate, you need to know the mass of the substance and its molar mass. Once you have the mass, divide it by the molar mass of sodium carbonate (105.99 g/mol) to find the number of moles. For example, if you have 10 grams of sodium carbonate, you would have 0.094 moles (10 g / 105.99 g/mol).
How many grams of iron are contained in 34 grams of fe2s3?
To calculate the amount of iron in Fe2S3, first find the molar mass of Fe2S3: Iron (Fe) has a molar mass of 55.85 g/mol and sulfur (S) has a molar mass of 32.06 g/mol. So, the molar mass of Fe2S3 is 2(55.85) + 3(32.06) = 222.92 g/mol. Next, divide the molar mass of iron by the molar mass of Fe2S3 and multiply by the given mass of Fe2S3 to find the grams of iron: (2 * 55.85 g/mol / 222.92 g/mol) * 34 g = 8.53 g of iron in 34 g of Fe2S3.
The formula for sodium carbonate is Na2CO3 Figure the molar mass of sodium carbonate to the nearest gram?
The molar mass of sodium carbonate (Na2CO3) can be calculated by adding the atomic masses of its constituent atoms. The atomic mass of Na is approximately 23 g/mol, C is approximately 12 g/mol, and O is approximately 16 g/mol. Therefore, the molar mass of Na2CO3 would be: 2(23) + 12 + 3(16) = 106 g/mol. Rounded to the nearest gram, the molar mass of sodium carbonate is 106 g/mol.
