A student requires 2.00 L of 0.100 M NH4NO3 from a 1.75 M NH4NO3 stock solution. What is the correct way to get the solution?
2 answers:
Answer : The volume of stock solution is, 0.114 L
Solution :
According to the dilution law,
where,
= molarity of
solution = 0.100 M
= volume of
solution = 2.00 L
= molarity of
stock solution = 1.75 M
= volume of
stock solution = ?
Now put all the given values in the above law, we get the volume of stock solution.
Therefore, the volume of stock solution is, 0.114 L

Answer: Option (c) is the correct answer.
Explanation:
A limiting reagent is defined as a reagent that completely gets consumed in a chemical reaction. A limiting reagent limits the formation of products.
For example, we have given 5 mol of A and the reaction is
Whereas when 4 mol B will react with 2 mol of A. Hence, 8 mol of B will react with 4 mol A as follows.
= 4 mol
As, the given moles of A is more than the required moles. Thus, it is considered as an excess reagent.
Hence, B is a limiting reagent because it limits the formation of products.
Thus, we can conclude that limiting reactant is the term used to describe the reactant that is used up completely and controls the amount of product that can be produced during a chemical reaction.
