Concept explainers
a.
To find: An expression for
The expression for concentration
Given information:
The amount of water added is
Formula used:
Concentration is equal to amount of acid over total volume
Calculations:.
Here total volume when
Concentration of acid is
So concentration
Hence expression for concentration
b.
To sketch : use a graph to determine amount of water should be added to get the solution is
Given information:
The concentration is
Concept used:
Take
Thus based on the graph amount of the water added to the concentration is
c.
To find : the amount of water should be added to get the solution is
The amount of water to get concentration
Given information:
The concentration is
Formula used:
Calculations:
Take
Substitute the value in to the equation:
Hence the amount of water to get concentration
