Answer:
I think the answer would be 'testable'.
The grams are in 0.0150 moles of caffeine C8H10N4O2
mass = moles of C8H10N4O2 x molar mass of C8H10N4O2
= 194g/mol x 0.0150mol = 2.91 grams
there is 2.94 grams in 0.01150 of caffeine
All of the F's sublevels, including the 5F contains 7 orbitals. Then, each orbital should contain 2 electrons. From the given above, the number of electrons in the sublevel is calculated through,
n = (7 orbitals) x (2 electrons / orbital) = 14 electrons
Thus, the 5F sublevel contains 14 electrons.
You have to take the 476 L and divide it by 22.4 because with Molar Volume 1 mol = 22.4L. After you divide it your answer is 21.25.
