THE MOLAR MASS OF CALCIUM OXALATE,CaC2O4 IS 128G/MOLE. WHAT % OF CARBON IS CALCIUM OXALATE?
To calculate the percentage of carbon in calcium oxalate (CaC2O4), you need to determine the molar mass of carbon in the compound and then divide it by the molar mass of calcium oxalate. Here's the step-by-step process to work it out:
1. Find the molar mass of carbon (C). Carbon has an atomic mass of approximately 12.01 g/mol.
2. Calculate the molar mass of calcium oxalate (CaC2O4). Given that the molar mass of calcium (Ca) is about 40.08 g/mol, the molar mass of carbon (C) is 12.01 g/mol, and the molar mass of oxygen (O) is 16.00 g/mol, the molar mass of calcium oxalate is:
Molar mass of CaC2O4 = (1 * atomic mass of Ca) + (2 * atomic mass of C) + (4 * atomic mass of O)
Molar mass of CaC2O4 = (1 * 40.08 g/mol) + (2 * 12.01 g/mol) + (4 * 16.00 g/mol)
Molar mass of CaC2O4 = 128.08 g/mol
3. Calculate the percentage of carbon (C) in calcium oxalate (CaC2O4) by dividing the molar mass of carbon by the molar mass of calcium oxalate and then multiplying by 100:
Percentage of carbon in CaC2O4 = (Molar mass of C / Molar mass of CaC2O4) * 100
Percentage of carbon in CaC2O4 = (12.01 g/mol / 128.08 g/mol) * 100
Percentage of carbon in CaC2O4 ≈ 9.37%
Therefore, the percentage of carbon in calcium oxalate is approximately 9.37%.
[Atomic mass C/molar mass CaC2O4]*100
Don't forget to multiply C*2.
