What is the molar mass of the potassium permanganate?

To find the molar mass of calcium carbonate (CaCO₃), follow these simple steps:

Step-by-Step Calculation:

Calcium carbonate has the chemical formula: CaCO₃

This means it contains:

• 1 atom of Calcium (Ca)
• 1 atom of Carbon (C)
• 3 atoms of Oxygen (O)

Atomic Masses (from the Periodic Table):

• Calcium (Ca) = 40.08 g/mol
• Carbon (C) = 12.01 g/mol
• Oxygen (O) = 16.00 g/mol

Now, add them up:

Molar mass of CaCO₃=(1×40.08)+(1×12.01)+(3×16.00)\text{Molar mass of CaCO₃} = (1 × 40.08) + (1 × 12.01) + (3 × 16.00)=40.08+12.01+48.00= 40.08 + 12.01 + 48.00=100.09 g/mol= \mathbf{100.09\ g/mol}

Final Answer: 100.09 g/mol
