A grocery store has 75 dozen packages of hotdogs In stock. If there are 10 hot dogs in each package, how many moles of hot dogs
is this?
2 answers:
Answer:
Explanation:
First we will calculate the amount of hot dog units we have:
-75 dozen packages (a dozen is 12 )=75x12=900 packages
-each package has 10 hot dogs=900x10=9000 hot dog units
We know a mole of something is units of that something. And that will be our conversion factor for this excercise. We will convert now from 9000 units of hot dogs to moles of hot dogs like this:

There are 7 values of ml are allowed for an electron in a 5f subshell namely: -3 -2, -1, 0, +1, +2, +3
<h3>Further explanation</h3>In an atom, there are energy levels in the shell and subshell.This energy level is expressed in terms of electron configurations.
Writing the electron configuration starts from the lowest to the highest subshell's energy level. There are 4 sub-shells in an atom's shell, namely s, p, d, and f. The maximum number of electrons for each subshell is
- s: 2 electrons
- p: 6 electrons
- d: 10 electrons and
- f: 14 electrons
Electron filling in subshells using the following sequence:
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.
Each sub-shell also has orbitals drawn in the form of a square box in which there are electrons symbolized by half arrows.
Each orbital in an atom consists of 4 quantum numbers
- n is the principal quantum number.
- l is the angular momentum / azimuthal quantum number
- ml, the magnetic quantum number
- ms, the electron-spin quantum number
Value of n: positive integer
value of l: s = 0, p = 1, d = 2, f = 3
ml value: between -l to + l
ms value: +1/2 or -1/2
Determination of electron configurations based on principles:
- 1. Aufbau: Electrons occupy orbitals of the lowest energy level
- 2 Hund: electron fills orbitals with the same energy level
- 3. Pauli: there are no electrons that have 4 equal quantum numbers
So for 5f orbitals, the value of a possible quantum number is
n = 5;
l = 3 (f = 3);
m = -3 -2, -1, 0, +1, +2, +3;
s = + - 1/2
