Final answer:
To find the number of grams of CaCO₃ in the sample, multiply the number of moles by the molar mass of CaCO₃.
Step-by-step explanation:
To determine the number of grams of CaCO₃ present in the sample, we need to use the molar mass of CaCO₃. The molar mass of CaCO₃ is equal to the sum of the atomic masses of calcium (Ca), carbon (C), and three oxygen (O) atoms:
Molar mass of CaCO₃ = (40.08 g/mol) + (12.01 g/mol) + (16.00 g/mol) x 3 = 100.09 g/mol
To find the number of grams, we can use the formula:
Grams = Moles x Molar mass
Grams of CaCO₃ = 4.52 moles x 100.09 g/mol = 452.24 g
