The total mass of the products can be calculated by adding up the individual 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.
Using the balanced chemical equation, we can see that 2 moles of sodium react with 1 mole of chlorine to produce 2 moles of sodium chloride.
Therefore, the total mass of the products can be calculated as follows:
2NaCl = (2Na + 1Cl2)
2(22.99 amu) + 35.45 amu = 45.98 amu + 35.45 amu = 81.43 amu
So, the total mass of the products will be 81.43 amu.
Therefore, the correct answer is:
81.43 amu
To find the total mass of the products, we need to calculate the molar mass of sodium chloride (NaCl). The molar mass of an element or compound is the mass of one mole of that substance.
The molar mass of sodium (Na) is 22.99 g/mol. Since we have 2 moles of sodium in the reaction (according to the balanced equation), the total mass of sodium is:
2 moles x 22.99 g/mol = 45.98 g
The molar mass of chlorine (Cl) is 35.45 g/mol. Since we have 1 mole of chlorine gas (Cl2) in the reaction (according to the balanced equation), the total mass of chlorine is:
1 mole x 35.45 g/mol = 35.45 g
Therefore, the total mass of the products (sodium chloride) is the sum of the masses of sodium and chlorine:
45.98 g + 35.45 g = 81.43 g
So, the total mass of the products is 81.43 g.
None of the provided options matches this result, so the correct answer is not among the given choices.
To determine the total mass of the products, we need to calculate the molar mass of sodium chloride (NaCl). The molar mass of an element or compound is the mass of one mole of that substance.
To find the molar mass of NaCl, we add the atomic masses of sodium (Na) and chlorine (Cl). The atomic mass of Na is approximately 22.99 amu, and the atomic mass of Cl is approximately 35.45 amu.
Therefore, the molar mass of NaCl is:
Na: 1 * 22.99 amu = 22.99 amu
Cl: 1 * 35.45 amu = 35.45 amu
Total: 22.99 amu + 35.45 amu = 58.44 amu
Since the chemical equation indicates that 2 moles of NaCl are produced from 2 moles of Na and 1 mole of Cl2, we can multiply the molar mass of NaCl by 2:
2 * 58.44 amu = 116.88 amu
Therefore, the total mass of the products will be 116.88 amu.
