To determine the number of moles of sodium chloride produced when 25 grams of sodium reacts with chlorine gas, we need to use the concept of stoichiometry.
First, we need to write the balanced chemical equation for the reaction between sodium metal and chlorine gas. The balanced equation is:
2 Na + Cl2 -> 2 NaCl
From the stoichiometry of the balanced equation, we can see that 2 moles of sodium react with 1 mole of chlorine gas to produce 2 moles of sodium chloride.
Next, we calculate the number of moles of sodium using its molar mass. The molar mass of sodium (Na) is approximately 22.99 g/mol.
Number of moles of sodium = Mass of sodium / Molar mass of sodium
= 25 g / 22.99 g/mol
≈ 1.09 mol
Since 2 moles of sodium react with 2 moles of sodium chloride, we can conclude that 1.09 moles of sodium will react to produce the same number of moles of sodium chloride.
Therefore, the number of moles of sodium chloride produced is approximately 1.09 moles.
