Question 71 - Review - Chapter 1

Problem:

The atomic mass of fissionable uranium is 235.0 g.

Question:

a) How much does one atom weigh in kg?
b) In Atomic mass unit?

Solution:

1 Atomic mass unit u = 1.66053904e-27 kg

weight of one atom = atomic mass * u

import numpy as np
import scipy.constants as physics
amu = physics.value('atomic mass constant')
am_u = 235.0; # gr
weight_u = am_u * amu;
print(f'\ta) Gewicht van één atoom U is {weight_u:.2e} kg');

	a) Gewicht van één atoom U is 3.90e-25 kg

    b) The weight of the atom in atomic mass units is, according to the definition, equal to the atomic mass 235
