The total mass of the reactants is 58.44 amu. According to the chemical equation, 2 moles of sodium (2Na) react with 1 mole of chlorine (Cl2) to form 2 moles of sodium chloride (2NaCl).
To find the total mass of the products, we can calculate the molar mass of sodium chloride (NaCl).
The molar mass of sodium (Na) is approximately 22.99 amu, and the molar mass of chlorine (Cl) is approximately 35.45 amu.
The molar mass of sodium chloride (NaCl) is the sum of the molar mass of sodium and chlorine, which is 22.99 amu + 35.45 amu = 58.44 amu.
Since 2 moles of sodium chloride are produced in the reaction, the total mass of the products is 2 moles x 58.44 amu/mole = 116.88 amu.
Therefore, the correct answer is 116.88 amu.
To determine the total mass of the products, we need to calculate the molar mass of sodium chloride (NaCl) and multiply it by the stoichiometric coefficient.
The molar mass of sodium chloride (NaCl) is calculated by adding the atomic masses of sodium (Na) and chlorine (Cl). The atomic mass of sodium (Na) is 22.99 amu and the atomic mass of chlorine (Cl) is 35.45 amu.
So the molar mass of NaCl is:
Molar mass NaCl = (atomic mass of Na) + (atomic mass of Cl)
= 22.99 amu + 35.45 amu
= 58.44 amu
From the balanced chemical equation, we can see that the stoichiometric coefficient of NaCl is 2. This means that for every 2 moles of sodium chloride formed, there are 2 moles of sodium (Na) and 1 mole of chlorine (Cl2) consumed.
Since the total mass of the reactants is given as 58.44 amu, which is the molar mass of NaCl, the total mass of the products will also be 58.44 amu.
Therefore, the correct answer is:
58.44 amu.
To determine the total mass of the products, we need to understand that in a chemical reaction, mass is conserved. This principle is known as the law of conservation of mass. It states that the total mass of the reactants is equal to the total mass of the products.
From the balanced chemical equation provided:
2Na + Cl2 → 2NaCl
We can see that for every 2 moles of sodium (Na), we need 1 mole of chlorine (Cl2) to react, and 2 moles of sodium chloride (NaCl) are produced.
To calculate the mass, we need the molar masses of each element. The atomic mass of sodium (Na) is approximately 22.99 amu, chlorine (Cl) is approximately 35.45 amu, and sodium chloride (NaCl) is approximately 58.44 amu.
Therefore, the molar mass of 2Na is 2 x 22.99 amu = 45.98 amu.
The molar mass of Cl2 is 1 x (35.45 amu x 2) = 70.9 amu.
The molar mass of 2NaCl is 2 x 58.44 amu = 116.88 amu.
Now, let's determine the total mass of the reactants:
45.98 amu (2Na) + 70.9 amu (Cl2) = 116.88 amu
So, the total mass of the reactants is 116.88 amu.
According to the law of conservation of mass, the total mass of the products will also be 116.88 amu.
Therefore, the correct answer is: 116.88 amu.
