### Finding KE

Use the uncertainty of velocity (delta v= 3.4E10) to calculate the electron's uncertainty in kinetic energy. Then, calculate the uncertainty in kinetic energy per mole of electrons (that is, per mole of hydrogen atoms).
Mass of electron is 9.1E-31 kg.

### Re: Finding KE

To calculate the electron's uncertainty in kinetic energy, you can use the formula KE=1/2mv^2. Next, you can multiply the electron's uncertainty in KE you found by Avogadro's number to find the uncertainty in KE per mole of electrons.
