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.

Question

H2 + Cl2 ---> 2HCl

Answer 1

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.
