So the correct answer is A?

Answer 3

Thanks:)

Answer 4

you have the same number of molecules in each case: about \(6.022*10^{23}\)
look at each molecule and count up the atoms to find the molecule that will give you the most atoms in a mole of that molecule.

A: \(\text{Al}_2(\text{SO}_4)^3 \rightarrow 2+3*(1+4*1)= 17\)
B: \(\text{C}_{10}\text{H}_8\rightarrow 10+8 = 18\)
C: \(\text{Cl}_2\rightarrow 2\)
D: \(\text{Na}_3\text{PO}_4\rightarrow 3+4=7\)
D:\(\text{S}_8\rightarrow8\)

Therefore, B is the correct answer, NOT A.
