Wastewater from a cement factory contains 0.410 g of ca2+ ion and 0.0330 g of mg2+ ion per 100.0 l of solution. the solution density is 1.001 g/ml. calculate the ca2+ and mg2+ concentrations in ppm (by mass).

= 4.0959 ppm

= 0.3296 ppm

Explanation:

ppm means milligram of solute per kilogram of solution.

Solutes:

Mass = 0.410g

Mass = 0.0330g

Solution: 100.0 L, whose density is 1.001 g/mL

First, let us to calculate mass of solution:

= 100.1 kg

Now, we have to calculate ppm

ppm

ppm

what is the question here. i think you messed up.

1 is the answer to this problem
