To solve this problem, we need to use the concept of stoichiometry and the molar mass of the substances involved.Given information:- The balanced chemical equation is:
- The mass of
is
- The molar mass of
is
- The molar mass of
is
Step 1: Calculate the number of moles of
.Number of moles of
= Mass of
/ Molar mass of
Number of moles of
=
Step 2: Use the stoichiometric relationship between
and
to find the number of moles of
produced.According to the balanced equation, 2 moles of
produce 3 moles of
.Number of moles of
produced =
Step 3: Calculate the mass of
produced.Mass of
= Number of moles of
× Molar mass of
Mass of
=
Therefore, the correct answer is:18.03 g
