Work = Fdcos(alpha)
Where F is force, D is distance, and Alpha is the angle to the parallel plane (in this case the ground)
I’ll assume alpha is 0 since it’s not given
100 • 12 • cos(0) = 1200 ft-lbs
The part that says all atoms of a specific element always have the same mass. Isotopes of an atom have varying masses compared to the standard version of the element.
will tell you the subshell type, so you are dealing with a d orbital.
ml will tell you the orientation of the orbital, there is no distinction between the orbitals so -1 doesnt specifically mean anything.
3( 2 carbons + 4 hydrogen's + 2 oxygens)
3*(8) = 24
