Answer #1

We know that %m/m is mass of solute per mass of solution in this case dioxin and contaminated water, respectively.

From density definition which is mass/volume, we calculate the mass of solution.

Now,

, substituting the value and clear mste (mass of solute) we obtain

In 3L of water there is 2.55g of dioxin.
