The Law of Conservation of Mass states "Mass cannot be created or destroyed, only transformed."

Question

Considering the Law of Conservation of Mass, 4 grams of Sodium (Na) will need to combine with how many grams of Cl (Chlorine) to produce 10 grams of Sodium Chloride?

Answer 1

To solve this problem, we can use the Law of Conservation of Mass, which states that the total mass of the reactants must equal the total mass of the products.

In this case, we are combining sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl). We would like to find out how many grams of chlorine (Cl) are needed to combine with 4 grams of sodium (Na) to produce a total of 10 grams of sodium chloride (NaCl).

1. Start with the total mass of sodium chloride that we want to produce: \[ \text{Mass of NaCl} = 10 \text{ grams (desired mass of product)} \]

2. Since we already have 4 grams of sodium (Na), we can find the mass of chlorine required using the conservation of mass: \[ \text{Mass of Na} + \text{Mass of Cl} = \text{Mass of NaCl} \] \[ 4 \text{ grams (mass of Na)} + \text{Mass of Cl} = 10 \text{ grams (mass of NaCl)} \]

3. Rearranging the equation to solve for the mass of chlorine: \[ \text{Mass of Cl} = 10 \text{ grams} - 4 \text{ grams} \] \[ \text{Mass of Cl} = 6 \text{ grams} \]

Thus, to produce 10 grams of sodium chloride, you will need to combine 4 grams of sodium (Na) with 6 grams of chlorine (Cl).
