Explanation:

Hello there!

In this case, in agreement to the definition of the pH, as the measure of the acidity and basicity of a substance; it is important to recall that pH's below 7 stand for acidic substances and pH's above 7 stand for basic substances, whereas a pH of 7 defines a neutral one. In such a way, given the pH's of the given substances, 7, 4.05 to 4.65, around 2.5, about 8.1 and about 8.3 respectively for sodium chloride, tomato juice, vinegar, sea water, bicarbonate of sodium​, it is possible to assert:

sodium chloride: neutral.

tomato juice: acid.

vinegar: acid.

sea water: base.

The atomic mass of potassium is 39.1. What is the mass of 6.02 × 1023 atoms of potassium? . . A.. 39.1 mg. . . . . B.. 39.1 g. .
Sholpan [36]
Atomic mass of Potassium = Mass of 1 atom of Potassium = 39.1 amu
Then
Mass of 6.02 x 1023 atoms of potassium = 39.1 x 6.02 x 1023 amu
                                                                  = 
We already know that
1 mole = 6.02 x 1023 atoms
Also
Number of mole = mass in grams/ atomic mass
Then
Mass in gram = Number of mole x atomic mass
                       = (39.1 x 6.02 x 1023)/(6.02 x 1023)
                       = 39.1 g
The correct option among all the options that are given in the question is the third option or option "B".
