In the reaction between H2 gas and I2 gas formed hydrogen io

In the reaction between H2 gas and I2 gas formed hydrogen iodide gas(HI) by equation:

H2(g) In2(g) 2HI (g)

If we leave 15.0 g H2 react with 15.0 g I2 and we assume that the reaction goes completely to

HI product, which gas is the limiting reactant and what is the mass of the product HI

formed?

given 15g H2 reacts with 15g I2

moles of H2 = 15/2 = 7.5moles

moles of I2 = 15/253.8 =0.0591 moles

but by reaction H2 + I2 ------> 2HI

so 1 mole of H2 reacts with 1 mole of I2

so here limiting reagent is I2 as after its 0.0591 moles are consumed reaction stops.
