Interpretation:
Whether two different solutions with different volumes can have same concentrations or not needs to be explained.
Concept introduction:
Concentration of a solution is expressed in different units. It can be g/ L of solute. It can be moles of solute per liter of solution. When concentration is taken in terms of mol/L, it is known as molarity.
Answer to Problem 1E
If amounts of solute are different then two different solutions can have same concentrations.
Explanation of Solution
Let’s consider one solution has 1 mol solute and volume is 1 L. Another solution has 2 mol solute and volume is 2 L.
For 1st solution molarity is 1/1=1.
For 2nd solution molarity is 2/2=1.
Thus, for both the solution the molarity is 1.
Thus, the ratio of number of moles and volume should be same for two solutions to have same concentartion.
