Answer:
Too high
Explanation:
The standarization of sodium hydroxide solution with potassium hydrogen phthalate consist in the addition of known quantity of moles of acid by weighing this solid.
If the solid is moist, the real mass of the acid will be less than weighed doing less the real moles of potassium hydrogen phthalate. Thus, in titration, volume of NaOH will be less than real volume and reported molar concentration will <em>be too high.</em>

Depending on what you need to round it to, it’s
1.9565
Or
1.957
Or
1.96
Density is mass/volume so it’s simply 4.8/2.3
Which equals
1.95652174
Hope this helped, good luck!
To answer this question, you need to understand the naming of meter unit system. The unit pm stands for pico meter which was 1/1000 of nanometer. Then, the calculation would be:
Number of atom= container length / atom diameter
Number of atom = 25 nm x (1000pm/nm) / 144pm= 173.6 atom
(K+ + MnO4- )+(K+ +Cl- )
This would be a one to one ratio as the charges of each component are equal
