So to solve for this, let us calculate first the mass of the solute based on 2 .25 parts per million concentration.
00:10
So just remember that ppm will be equivalent to the mass of the solute divided by the mass of the solution.
00:17
Mass solution.
00:19
Okay.
00:20
And then we multiply, so this is parts per million, multiply 1 million or 10 to the 6.
00:24
So we have 2 .25 ppm, right, divided by 10 to the 6.
00:30
And then our unknown here is the mass of the solution.
00:33
And the mass of the solution, the volume is we have 100 ,000 liters, rather, i'm so sorry.
00:43
It's 100 ,000 liters of solution...
