How many atoms are in marble?

Marble is primarily composed of calcite (calcium carbonate, CaCO₃), which consists of three types of atoms: calcium (Ca), carbon (C), and oxygen (O). Each molecule of calcite contains one calcium atom, one carbon atom, and three oxygen atoms, totaling five atoms per molecule. To determine the number of atoms in a specific piece of marble, you would need to know its mass and use the molar mass of calcite to calculate the number of molecules and then multiply by five. Therefore, the total number of atoms varies significantly based on the size and mass of the marble sample.
