calculate the mass of sodium chloride produced when 5.50 moles of sodium reacts in excess chlorine gas.

To calculate the mass of sodium chloride produced, you need to use the molar ratio between sodium and sodium chloride. The balanced chemical equation for the reaction is:

2 Na + Cl2 → 2 NaCl

From the equation, it can be observed that 2 moles of sodium react to produce 2 moles of sodium chloride.

Given that you have 5.50 moles of sodium, you can set up a proportion to find the corresponding amount of sodium chloride produced:

(5.50 moles Na) / (2 moles NaCl) = (X moles NaCl) / (1 mole Na)

Cross-multiplying, you get:
(5.50 moles Na) * (1 mole NaCl) = (2 moles NaCl) * (X moles Na)
5.50 moles NaCl = 2X moles NaCl

Dividing both sides by 2, you find that the molar amount of sodium chloride is 2.75 moles.

To convert moles into grams, you need to use the molar mass of sodium chloride (NaCl), which is approximately 58.44 g/mol.

To find the mass of sodium chloride produced, you can use the equation:

Mass = moles x molar mass
Mass = 2.75 moles x 58.44 g/mol

So the mass of sodium chloride produced when 5.50 moles of sodium reacts in excess chlorine gas is approximately 160.71 grams.

To calculate the mass of sodium chloride produced, you need to know the balanced chemical equation for the reaction between sodium and chlorine gas:

2 Na + Cl2 → 2 NaCl

From the equation, you can see that two moles of sodium react with one mole of chlorine gas to produce two moles of sodium chloride.

Since 5.50 moles of sodium are given and the reaction is in excess chlorine gas, the number of moles of sodium chloride produced will also be 5.50 moles.

To calculate the mass of sodium chloride, you need to know the molar mass of sodium chloride, which is the sum of the atomic masses of one sodium atom (Na) and one chlorine atom (Cl). The atomic mass of sodium (Na) is 22.99 g/mol and the atomic mass of chlorine (Cl) is 35.45 g/mol.

Thus, the molar mass of sodium chloride (NaCl) is:

22.99 g/mol (Na) + 35.45 g/mol (Cl) = 58.44 g/mol

Now you can calculate the mass of sodium chloride produced using the equation:

Mass = Moles × Molar Mass

Mass of sodium chloride = 5.50 moles × 58.44 g/mol = 321.42 g

Therefore, the mass of sodium chloride produced when 5.50 moles of sodium react in excess chlorine gas is 321.42 grams.

2Na + Cl2 ==> 2NaCl

5.5 mols Na x (2 mols NaCl/2 mols Na) = 5.5 mols Na x 2/2 = 5.5 mols NaCl.

Convert to grams. g = mols x atomic mass.
