To what volume should you dilute 50ml of a 13M stock HNO3 solution to obtain a 0.131M HNO3 solution?
c1v1 = c2v2
To calculate the volume to which you should dilute a solution, you can use the equation:
M1V1 = M2V2
Where:
M1 = initial concentration of the solution (in this case, the concentration of the stock solution)
V1 = initial volume of the solution (in this case, 50 ml of the stock solution)
M2 = final concentration of the solution (in this case, 0.131 M)
V2 = final volume of the solution (this is what we need to calculate)
Using the equation, we can rearrange it to solve for V2:
V2 = (M1V1) / M2
Now we can substitute the given values:
V2 = (13 M * 50 ml) / 0.131 M
V2 ≈ 4954.2 ml
Therefore, you would need to dilute 50 ml of the 13M HNO3 solution to a final volume of approximately 4954.2 ml (or 4.9542 liters) to obtain a 0.131M HNO3 solution.
