For the following reaction, 0.308 grams of hydrogen gas are allowed to react with 43.2 grams of iodine. hydrogen(g)+ iodine(s) yields hydrogen iodide(g) What is the maximum mass of hydrogen iodide that can be formed? ______? What is the formula for limiti

I'm assuming you're referring to this reaction,

#H_2(g) + I_2(g) rightleftharpoons 2HI(g)#

Given,

#n_(I_2) = 43.2"g" * "mol"/(253.8"g") approx 0.170"mol"#

#n_(H_2) = 0.308"g" * "mol"/(2.02"g") approx 0.152"mol"#

We conclude hydrogen gas is the limiting reactant.

Hence,

#0.152"mol" * (2HI)/(H_2) * (127.9"g")/(HI) approx 3.90"g"#

is the maximum mass of hydrogen iodide gas able to be produced.
