What volume of 15.6M NH4OH is needed to make 500.0 mL of 3.00M solution? a) 0.962 L b) 0.00962 L c) 0.026 L d) 0.0962 L

d) 0.0962 L

Explanation:

The problem describes a dilution process, meaning that we can solve it by using the following equation:

Where subscript 1 stands for the volume and concentration of the concentrated solution, and 2 for those of the diluted solution. That means that in this case:

We input the data:

And solve for V₁:

Finally we convert 96.2 mL to L:

The answer is thus option d).

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
