To calculate the molar mass of silver carbonate (Ag₂CO₃) easily, we need to first understand its molecular composition. Silver carbonate consists of two silver (Ag) ions, one carbon (C) atom, and three oxygen (O) atoms. Here’s how you can determine the molar mass step-by-step.
Step 1: Identify the Molar Mass of Each Element
The first step involves finding the molar mass of each element in the compound. The molar masses of the elements are as follows (in grams per mole):
- Silver (Ag): 107.87 g/mol
- Carbon (C): 12.01 g/mol
- Oxygen (O): 16.00 g/mol
Step 2: Multiply by the Number of Atoms in the Compound
Next, you need to multiply the molar mass of each element by the number of times it appears in the formula of silver carbonate:
- For Ag: 2 atoms x 107.87 g/mol = 215.74 g/mol
- For C: 1 atom x 12.01 g/mol = 12.01 g/mol
- For O: 3 atoms x 16.00 g/mol = 48.00 g/mol
Step 3: Add the Values Together
Now, we sum the total contributions from each of the elements:
- Total mass = (215.74 g/mol) + (12.01 g/mol) + (48.00 g/mol)
[ \text{Total mass} = 215.74 + 12.01 + 48.00 = 275.75 \text{ g/mol} ]
Conclusion
The molar mass of Ag₂CO₃ (silver carbonate) is 275.75 g/mol.
