How to do thus

**General Chemistry 4th Edition**

**McQuarrie · Rock · Gallogly**

**University Science Books presented by Macmillan Learning**

To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object. What kinetic energy, \( E_k \), must the electrons have in order to resolve a protein molecule that is 2.00 nm in diameter? Take the mass of an electron to be \( 9.11 \times 10^{-31} \) kg.

\[ E_k = \] \_\_\_\_\_\_\_\_\_\_\_\_\_ J

**Question Source:** McQuarrie, Rock, And Gallogly 4e - General Chemistry

**Publisher:** University Science Books

**Additional Details:**

The problem does not include any graphs or diagrams. The task involves calculating the kinetic energy needed for electron microscopy using given variables.

Expert Solution

Step 1

Given that :

The diameter of protein molecule = 2.00 nm

The mass of the electron = 9.11 x 10^-31 kg

We have to calculate the kinetic energy which the electron must-have.
