Answer:
[tex]m_{Fe}=71.982 kg[/tex]
Explanation:
First of all, we need to calculate the moles of H2. Assuming the H2 is an ideal gas:
[tex]n=\frac{P*V}{T*R}[/tex]
[tex]n=\frac{1atm*31100L}{294K*0.082 L*atm*mol^{-1}*K^{-1}}[/tex]
[tex]n=1290 mol[/tex]
Now, to produce 1 mol of H2 is required 1 mol of Fe:
[tex]m_{Fe}=n*M=1290mol*\{55.8 g}{mol}[/tex]
[tex]m_{Fe}=71982 g=71.982 kg[/tex]
The study of chemicals and bonds is called chemistry. There are two types of elements are there and these are metals and nonmetals.
The correct answer is 71.982kg.
What is ideal gas law?
- The ideal gas law, also called the general gas equation, is the equation of the state of a hypothetical ideal gas.
- It is a good approximation of the behavior of many gases under many conditions, although it has several limitations.
The formula used as:-
[tex]n=\frac{P*V}{T*R} \\\\n=\frac{1*31100}{294*0.082} \\\\\\n=1290moles[/tex]
The mass will be:-
[tex]M= n*M\\1290*55.8\\\\=71.982[/tex]
Hence, the correct answer is 71.982.
