Science: In a reaction, 12.99 grams of sodium reacts with 45.75 grams of chlorine. According to the law of conservation, how ma A. 29.37 grams B. 32.76 grams C. 58.74 grams D. 91.50 grams

To determine the mass involved in the reaction according to the **Law of Conservation of Mass**, we need to consider that mass is neither created nor destroyed in a chemical reaction. This means the total mass of the reactants equals the total mass of the products. **Given:** - Mass of sodium (Na) = 12.99 grams - Mass of chlorine (Cl₂) = 45.75 grams **Total Mass of Reactants:** \[ \text{Total Mass} = \text{Mass of Na} + \text{Mass of Cl}_2 \] \[ \text{Total Mass} = 12.99 \, \text{g} + 45.75 \, \text{g} \] \[ \text{Total Mass} = 58.74 \, \text{g} \] According to the Law of Conservation of Mass, the total mass of the products will also be **58.74 grams**. **Answer:** **C. 58.74 grams**
