I don't know much about the potential difference but I certainly can calculate the energy of the proton <span>from rest to 10% of the speed of light.

Special relativity tells us that "</span><span>the energy needed to accelerate a particle (with mass) grow super-quadratically when the speed is close to c, and is ∞ when it is c."

Expressed the theory in equation is as follows:
</span>
ENERGY  = rest mass × speed of light squared / (1−(“percent of speed of light”)squared ) <span> = mc2/(1-("percent of speed of light")2)
</span>
Just plug-in the values and you can now have the answer what you are looking for!

Calculating grams:
Alex_Xolod [135]

Answer:

The answer to your question is 55.224 g of NiCl₂

Explanation:

I will solve it and then I compare the results.

Data

Volume = 0.8 l

Molarity = 0.531

substance = NiCl₂

Process

1.- Calculate the molar mass of NiCl₂

NiCl₂ = 59 + (35.5 x 2)

         = 130 g

2.- Calculate the number of moles

Molarity = moles / volume

-Solve for moles

  moles = Molarity x volume

-Substitution

  moles = 0.531 x 0.8

-Result

  moles = 0.4248

3.- Convert the moles to mass

                   130 g -------------------- 1 mol of NiCl₂

                      x     -------------------- 0.4248 moles

                           x = (0.4248 x 130) / 1

-Simplifying

                         x = 55.224 / 1

-Result

                        x = 55.224 g of NiCl₂

4.- We need 55.224 g of NiCl₂ to prepare 0.8l of a solution 0.531 M.

You have similar results, just our molar mass is different.
