To calculate the mass of each reactant required to produce 25.0 mol of sodium chloride (NaCl), we need to use stoichiometry based on the balanced chemical equation:
From the equation, we see that 2 moles of Na react with 1 mole of Cl
to produce 2 moles of NaCl.First, determine the moles of each reactant needed to produce 25.0 moles of NaCl:- Since 2 moles of Na produce 2 moles of NaCl, 25.0 moles of NaCl will require 25.0 moles of Na.- Since 1 mole of Cl
produces 2 moles of NaCl, 25.0 moles of NaCl will require 12.5 moles of Cl
.Next, convert the moles of each reactant to grams using their molar masses:- Molar mass of Na = 22.99 g/mol- Molar mass of Cl
= 70.90 g/molCalculate the mass of Na:
Calculate the mass of Cl
:
Therefore, to produce 25.0 moles of sodium chloride, you would need:- 574.75 grams of sodium (Na)- 886.25 grams of chlorine gas (Cl
