Answer :
Final answer:
The new concentration of the KNO3 solution is 1.5M after being diluted to 3.0L from a 9.0M solution with a volume of 0.50L.
Explanation:
To find the new concentration of the solution, we can use the formula:
C1V1 = C2V2
Where C1 is the initial concentration, V1 is the initial volume, C2 is the new concentration, and V2 is the new volume.
Plugging in the values:
(9.0M)(0.50L) = C2(3.0L)
Simplifying the equation:
C2 = 1.5M
Therefore, the new concentration of the solution is 1.5M.
