Solution

$Λ^{\infty} (B a C l_{2}) = 280 S c m^{2}$ ${mol}^{- 1}$

$Λ^{\infty} (H_{2} S O_{4}) = 860 S c m^{2}$ ${mol}^{- 1}$

$Λ^{\infty} (H C l) = 426 S c m^{2}$ ${mol}^{- 1}$

$Λ^{\infty} (B a S O_{4}) = Λ^{\infty} (B a C l_{2}) + Λ^{\infty} (H_{2} S O_{4}) - 2 Λ^{\infty} (H C l)$

$Λ^{\infty} (B a S O_{4}) = 280 + 860 - 2 \times 426$

$Λ^{\infty} (B a S O_{4}) = 288 S c m^{2}$ ${mol}^{- 1}$
