The formed HCl concentration is 17.6g, and the limiting reactant is hydrogen.
<h3>What is limiting reactant?</h3>
In this case, based on the information provided, we can calculate the required grams of HCl by first identifying the limiting reactant using the moles of each reactant, which are in a 1:1 mole ratio:
nH₂ = .490gH₂ x 1 mol H₂ / 2.02g H₂ = 0.242 mol H₂
nCl₂ = 50.0gCl₂ x 1 mol Cl₂ / 70.9g Cl₂ = 0.705mol Cl₂
As a result, we conclude that hydrogen is the limiting reactant, and we use a 1:2 mole ratio with HCl, whose molar mass is 36.46 g/mol:
mHCl = .242 mol H₂ x 2mol HCl / 1 mol H₂ x 36.6g HCl / 1mol HCl
mHCl = 17.6g HCL
Therefore the concentration of HCl formed is 17.6g and the limiting reactant is hydrogen.
