Answer:
The number of moles is 0.15 moles
Explanation:
Given data
The volume of the solution is 25.0 mL = 25 *10^-3 L
The molarity of the solution is 6.0 M
This means the number of moles in this solution is: 6.0 M * 25 *10^-3 L = 0.15 moles
This solution will be diluted, by increasing its volume to 100 mL = 100*10^-3 L
The new solution has 0.15 moles in 100 mL
The Molarity of this solution will change, but the number of moles will not change.
The number of moles is still 0.15 moles
