To solve this problem, we need to use the concept of stoichiometry and the molar mass of the compounds involved.Given information:- The balanced chemical equation is:
- The molar masses are:
,
,
Step 1: Calculate the molar mass of
.Molar mass of
g/molStep 2: Calculate the number of moles of
.Number of moles of
Step 3: Use the stoichiometry of the balanced equation to find the number of moles of
.According to the balanced equation, 3 moles of
produce 2 moles of
.Number of moles of
Step 4: Calculate the molar mass of
.Molar mass of
g/molStep 5: Calculate the mass of
produced.Mass of
Therefore, the correct answer is 270.435 g of
.The closest option to this value is 243 g, so the correct answer is 243 g.
