![**Problem Statement:**
What volume of hydrogen gas is produced when 85.1 g of iron reacts completely according to the following reaction at 25 °C and 1 atm?
\[ \text{iron}(s) + \text{hydrochloric acid}(aq) \rightarrow \text{iron(II) chloride}(aq) + \text{hydrogen}(g) \]
**Solution Requirements:**
- **Volume:** \( \_\_\_\_ \) L
- **Buttons Available:**
- **Submit Answer**
- **Retry Entire Group**
**Additional Information:**
- The problem considers conditions at 25 °C and 1 atm for the reaction.
- The student is allowed 9 more attempts for the group of problems.
The interface provides a form for input, featuring navigational buttons for submitting and retrying the problem group.
**Educational Note:**
This problem requires an understanding of stoichiometry and gas laws to determine the volume of hydrogen gas produced. Students should consider the molar mass of iron, the stoichiometry of the reaction, and use the ideal gas law if necessary to find the volume under the given conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F18395f57-75e3-4bdb-980a-ed8850989594%2Fed87c036-bd0e-48d1-a32d-270b54d7cc8d%2Foo4ofdv_processed.jpeg&w=3840&q=75)
