Convert 5.85 L H2 to moles. moles = L/22.4.
Using the coefficients in the balanced equation, convert moles H2 to mols HCl.
Now convert moles HCl to grams. g = moles x molar mass.
Calculate the mass in grams of hydrgen chloride produced when 5.85 L of molecular hydrogen measured at STP reacts with an excess of molecular chlorine gas.
