first we need to find p, momentum.
e_kinetic = p^2/2m
p = sqrt(2m * e_kinetic)
p = sqrt(2 9.1110^(-31) 3.210^(-22)) = 2.41*10^(-26)
p: sup

now plug in your numerical values to find the value of the constant.
constant = j x s

Explanation:

Step1: Recall de - Broglie relation

The de - Broglie relation is $\lambda=\frac{h}{p}$, where $h$ is Planck's constant, $\lambda$ is the wavelength and $p$ is the momentum. We can rewrite it as $p=\frac{h}{\lambda}$, or $h = p\lambda$. So the constant that relates $p$ with $\lambda$ is Planck's constant $h$.

Step2: Provide the value of Planck's constant

The value of Planck's constant $h = 6.626\times10^{-34}\ J\cdot s$.

Answer:

$6.626\times 10^{-34}$
