To find the final volume of the solution, you need to subtract the change in volume from the initial volume.
Starting with 135 milliliters and a change of -58 milliliters:
Final Volume = Initial Volume + Change in Volume
Final Volume = 135 milliliters + (–58 milliliters)
Final Volume = 135 milliliters - 58 milliliters
Final Volume = 77 milliliters
Therefore, the final volume of the solution is 77 milliliters.
