For this problem we use the Avogadro's number which is an empirical value that relates the number of particles to the number of moles. Its approximated value is 6.022×10²³ atoms/mole. The solution is as follows:

4.40×10²⁴ aluminum atoms * 1 moles/6.022×10²³ atoms = 7.306

Thus, there are 7.306 moles of aluminum.

The diagram shows a simple lipid.
kifflom [539]
This is not a phospholipid as it does not contain a phosphate group at the end of the chain, and is not a triglyceride as there is no glyceryl moiety. Each carbon bonded to hydrogens makes the maximum number of C-H bonds possible, therefore there are no multiple bonds between carbons and the lipid is saturated. Therefore the answer is A.
Hope this helps!
