To determine how many moles of
are required to produce 2.5 moles of
, we need to use the stoichiometric relationship from the balanced chemical equation:
From the equation, we see that 2 moles of
produce 1 mole of
. Therefore, the ratio of
to
is 2:1.Given that we need to produce 2.5 moles of
, we can set up the proportion:
Solving for
:
So, 5.0 moles of
are required to produce 2.5 moles of
.The correct answer is:D. 5.0 mol
