mass of 488 mol of calcium carbonate

1 answer

To find the mass of 488 moles of calcium carbonate, we need to multiply its molar mass by the number of moles.

The molar mass of calcium carbonate (CaCO3) is:

1 atom of calcium = 40.08 g/mol
1 atom of carbon = 12.01 g/mol
3 atoms of oxygen = 3 x 16.00 g/mol = 48.00 g/mol

So, the molar mass of CaCO3 is:

40.08 + 12.01 + 48.00 = 100.09 g/mol

Therefore, the mass of 488 moles of calcium carbonate is:

488 mol x 100.09 g/mol = 48,866.32 g or 48.87 kg (to two decimal places)
