Final answer:

To find the number of moles in 3.00 kg of CaCO3, divide the mass in grams by the molar mass of CaCO3.

Step-by-step explanation:

To calculate the number of moles in 3.00 kg of CaCO3, we need to use the molar mass of CaCO3. The molar mass of CaCO3 is 100.09 g/mol. First, we convert the mass of CaCO3 from kg to grams by multiplying it by 1000: 3.00 kg * 1000 = 3000 g. Then, we divide the mass in grams by the molar mass to find the number of moles: 3000 g / 100.09 g/mol = 29.98 moles. Therefore, there are approximately 30 moles in 3.00 kg of CaCO3.

Step-by-step explanation:

Molar mass of CaCO3= 100 g/mol

Given mass = 3kg= 3000 g

No of moles = 3000/100=30 mol
