Final answer:
The molar mass of copper carbonate is 123.54 g/mol. Therefore, the mass of 3.1*10^24 formula units of copper carbonate is 3.81 x 10^26 g.
Step-by-step explanation:
To find the mass of 3.1*10^24 formula units of copper carbonate, we need to calculate the molar mass of copper carbonate and then multiply it by the number of formula units.
The molar mass of copper carbonate (CuCO3) can be calculated by adding the atomic masses of copper (Cu), carbon (C), and oxygen (O). The atomic mass of copper is 63.54 g/mol, carbon is 12.01 g/mol, and oxygen is 16.00 g/mol.
Therefore, the molar mass of copper carbonate is: (63.54 + 12.01 + (3 x 16.00)) g/mol = 123.54 g/mol
Now, we can calculate the mass of 3.1*10^24 formula units of copper carbonate:
Mass = Number of formula units x Molar mass
Mass = (3.1*10^24) x (123.54 g/mol)
Using the proper scientific notation:
Mass = 3.81 x 10^26 g
