♥ Mixture refers to any substance which is composed of molecules of different types.
♥ The different elements and compounds in the mixture retain their original physical properties even after combining to form a mixture.
The second approach is correct. The other two approaches are not correct because they are incomplete; first approach would have been right IF the 6.0 ppm was MEASURED in hexane. Third approach cannot be right since it calculates moles and grams but not L.
Answer:
it is the only one going up
Explanation:
The concentration of hydrogen can be shown as:
[H+ ] = 3 * 10-5 M
pH can be determined as:
pH = - log [H+ ]
= - log (3 * 10-5)
= 4.53
Thus the pH of solution is 4.53
