Under certain conditions the rate of this reaction is zero order in ammonia with a rate constant of 0.0027 M.s → 2 NH3 (9) N2 (g) + 3H2(g) -1

A gas is formed in the reaction shown below. The gas laws can help determine the volume of gas produced. Zn(s) + 2 HCl(aq) → ZnCl₂ + H₂(g) Assume that 131.0 grams of Zn was used in this reaction. To determine the number of moles of hydrogen gas formed, you need to know the number of moles of Zn reactant was used. How many moles of Zn were used?
