Chemical Reaction: CS2 and Oxygen

When discussing chemical reactions, understanding the molar mass of the reactants is crucial. In this case, the molar mass of CS2 is 76.14 g/mol, while the molar mass of O2 is 32 g/mol.

The molar mass of a compound is the sum of the atomic masses of all the elements in the compound. For carbon disulfide (CS2), the molecular formula consists of one carbon atom (C) with an atomic mass of approximately 12.01 g/mol and two sulfur atoms (S) with atomic masses of around 32.07 g/mol each. Therefore, the molar mass of CS2 can be calculated as:

Molar mass of CS2 = 1(12.01 g/mol) + 2(32.07 g/mol) = 76.14 g/mol

Similarly, for oxygen gas (O2), the molecular formula consists of two oxygen atoms with individual atomic masses of 16 g/mol. The molar mass of O2 is then calculated as:

Molar mass of O2 = 2(16 g/mol) = 32 g/mol

Having this information allows us to accurately determine the amount of reactants needed for a chemical reaction and predict the products formed. The molar mass of each substance also plays a role in stoichiometry calculations to establish the relationships between reactants and products in a reaction.
