Which of the following expressions correctly represents the equivalent conductance at infinite diluation of Al₂(SO₄)₃. Given that $$\mathop \Lambda \limits^ \circ $$_Al³⁺ and $$\mathop \Lambda \limits^ \circ $$_{so$$_4^{2 - }$$} are the equivalent conductances at infinite dilution of the respective ions?

$$2\mathop \Lambda \limits^ \circ $$_Al³⁺ + $$3\mathop \Lambda \limits^ \circ $$_{so$$_4^{2 - }$$}

$$\mathop \Lambda \limits^ \circ $$_Al³⁺ + $$\mathop \Lambda \limits^ \circ $$_{so$$_4^{2 - }$$}

($$\mathop \Lambda \limits^ \circ $$_Al³⁺ + $$\mathop \Lambda \limits^ \circ $$_{so$$_4^{2 - }$$}) $$ \times $$ 6

$${1 \over 3}$$$$\mathop \Lambda \limits^ \circ $$_Al³⁺ + $${1 \over 2}$$$$\mathop \Lambda \limits^ \circ $$_{so$$_4^{2 - }$$}
