2.0L of a 2.0M HCl solution is added to water so that the final volume is 6.0L
Valencias are great oranges -- but what do they have to do with chemistry?
To find the final concentration of the HCl solution after it is diluted, we can use the equation:
M1V1=M2V2
Where M1 is the initial concentration of the solution, V1 is the initial volume of the solution, M2 is the final concentration of the solution, and V2 is the final volume of the solution.
Given:
Initial concentration (M1) = 2.0 M
Initial volume (V1) = 2.0 L
Final volume (V2) = 6.0 L
Now we can plug in the values into the equation and solve for M2:
(2.0 M)(2.0 L) = (M2)(6.0 L)
4.0 mol = (M2)(6.0 L)
Next, we can isolate M2 by dividing both sides of the equation by 6.0 L:
(M2) = 4.0 mol / 6.0 L
M2 = 0.67 M
Therefore, the final concentration of the HCl solution after it is diluted is 0.67 M.
