The theoretical yield of H₂S is 13.5 g.
The percent yield is 75.5 %.
<h3>What is the theoretical yield of H₂S from the reaction?</h3>
The equation of the reaction is given below:
Moles of FeS reacting = mass/molar mass
Molar mass of FeS = 88 g/mol
Moles of FeS reacting = 35/88 = 0.398 moles
Moles of H₂S produced = 0.398 moles
Molar mass of H₂S = 34 g/mol
Mass of H₂S produced = 0.398 * 34 = 13.5 g
Theoretical yield of H₂S is 13.5 g.
- Percent yield = actual yield/theoretical yield * 100%
Actual yield of H₂S = 10.2 g
Percent yield = 10.2/13.5 * 100%
Percent yield = 75.5 %
In conclusion, the actual yield is less than the theoretical yield.

Answer : The molarity of the new solution is, 4.069 M
Solution : Given,
Molarity of KOH solution = 4 M
Volume of KOH solution = 2.5 L
Volume of water added = 1.8 L
First we have to calculate the volume of new solution.
Volume of new solution = volume of KOH solution + volume of water added
Volume of new solution = 2.5 L + 1.8 L = 4.3 L
Now we have to calculate the molarity of the new solution.
Formula used :
where,
= molarity of KOH solution
= molarity of new solution
= volume of KOH solution
= volume of new solution
Now put all the given values in the above formula, we get the molarity of the new solution.
Therefore, the molarity of the new solution is, 4.069 M
The United States Code refers to these units as "traditional systems ofweights and measures". Other common ways of referring to the system in the U.S. are: "Standard", "Customary", or, erroneously: "Imperial", or "English" (which refers to the pre-1824 reform measures used throughout the British Empire).
If its a acid it will be 3 or if its a alkali then 14 or neutral then 7
Carbon consists of 6 protons and 8 neutrons so the atomic number is 6
