What is the molar mass of Al (ClO4) 3?
Molar mass of Al(ClO4)3 is 325.3333 g/mol. Formula in Hill system is AlCl3O12. Elemental composition of Al(ClO4)3:
What is the enthalpy of formation of Al (ClO4) 3 and CH3OH?
"Addition of solid Al (ClO4)3 to CH3OH at [around] 20 °C leads to a flash." In another paper by the same researchers, the enthalpy of formation of anhydrous aluminum perchlorate was experimentally determined to be -136.5 ±0.5 kcal/mole.

What happens when Al (ClO4) 3 is treated with THF?
Treatment of Al (ClO4)3 with THF leads to formation of a poorly soluble solvate of the composition Al (ClO4)3 • 3C4H8O; its IR spectrum does not display bands of the ClO4- ion, but it has bands of the ClO4 coordinated group: 920, 1040,and 1200 cm-1.

Answer
It would be +7 oxidation number. (All compounds are zero) Al is in group lll ( or 13 depending on the system) so the oxidation state is 3. You have 12 O at -2 each for -24. That leaves you at -24+3= -21. So 3 Cl atoms must be +21 to balance the -21 there which makes +21/3 or +7 for each Cl.
Answer
As per the rule for assigning oxidation number, the oxidation number of Al and O is +3 and -2 respectively.
