1. Understand the Chemical Formula

* CS₂ represents the compound carbon disulfide.

* The subscript "2" indicates that there are two sulfur (S) atoms for every one carbon (C) atom in the molecule.

2. Convert Grams to Moles

* You need to know the molar mass of CS₂ to convert grams to moles.

* Molar mass of carbon (C) = 12.01 g/mol

* Molar mass of sulfur (S) = 32.07 g/mol

* Molar mass of CS₂ = 12.01 g/mol + (2 * 32.07 g/mol) = 76.15 g/mol

3. Calculate Moles of CS₂

* You haven't provided the mass of CS₂ (3.00 cs2 doesn't make sense as a unit). Let's assume you meant 3.00 grams of CS₂.

* Divide the mass by the molar mass:

* Moles of CS₂ = 3.00 g / 76.15 g/mol = 0.0394 mol CS₂

4. Calculate Moles of Sulfur Atoms

* Since there are two sulfur atoms per molecule of CS₂, multiply the moles of CS₂ by 2:

* Moles of sulfur atoms = 0.0394 mol CS₂ * 2 mol S/mol CS₂ = 0.0788 mol S

Therefore, there are 0.0788 moles of sulfur atoms in 3.00 grams of CS₂.
