Sodium reacts with chlorine to form the compound sodium chloride, or salt. The chemical formula below shows how the two elements combine into a compound.
2Na + Cl2 → 2NaCl
If the total mass of the reactants is 58.44 amu, what will be the total mass of the products?
29.22 amu
116.88 amu
60 amu
58.44 amu
To determine the total mass of the products, we need to first calculate the molar mass of sodium chloride using the atomic masses from the periodic table.
The atomic mass of sodium (Na) is 22.99 amu and the atomic mass of chlorine (Cl) is 35.45 amu.
The molar mass of sodium chloride (NaCl) is: 22.99 amu + 35.45 amu = 58.44 amu.
Since the reaction produces 2 moles of sodium chloride (NaCl), the total mass of the products is: 2 moles x 58.44 amu = 116.88 amu.
So, the correct answer is 116.88 amu.
