Water that contains large amounts of disolved salts
Answer:

Explanation:
Hello.
In this case, we can compute the percent composition of chlorine as shown below:

Whereas the atomic mass of chlorine is 35.45 g/mol and the molar mass of C₂H₂Cl₂ is 96.95 g/mol, thus, the percent composition turns out:

Best regards.
Answer:
I think its the first one
Explanation:
Answer:
solute
Explanation:
The substance being dissolved is called a solute. The thing the solute is being dissolved in is called a solvent.
The solution for the problem is:
First, use the concentration of the volume of the thing you
know to compute for the moles of that substance. Then, use the coefficient in
the balanced equation to relay moles of that to moles of anything else in the
chemical equation. Lastly, translate moles into mass by means of its molar
mass, or into a concentration using the volume.
Applying what I have said earlier:
0.0133 L X 1.68 mol/L = 0.0223 mol KMnO4 X (1 mol H2O2 / 2
mol KMnO4) = 0.0112 mol H2O2
Mass H2O2 = 0.0112 mol H2O2 X 34.0 g/mol = 0.380 grams H2O2
