Answer
To calculate the relative formula mass of CuCO₃, we can sum the atomic masses of each constituent element:
Copper (Cu): 63.5
Carbon (C): 12.0
Oxygen (O): 16.0 (there are 3 oxygen atoms)
Thus, the calculation is as follows:
63.5+12.0+(3imes16.0)=63.5+12.0+48.0=123.5
Therefore, the relative formula mass of CuCO₃ is 123.5.
