Final answer:
To calculate 75 mol of CaCO₃, multiply the number of moles by the molar mass of CaCO₃.
Step-by-step explanation:
To calculate the number of moles in 75 mol of CaCO₃, we need to use the formula:
Number of moles = mass / molar mass
The molar mass of CaCO₃ is 100.087 g/mol. We can calculate the mass by multiplying the number of moles (75) by the molar mass:
Mass = 75 mol * 100.087 g/mol
Mass = 7506.525 g
Therefore, 75 mol of CaCO₃ is equal to 7506.525 grams.
