A)4.8 × 10^-24 B)6.3 × 10^-23 C)1.6 × 10^-6 D)1.4 × 10¹⁵

Question

The relationship between K_n, K_a, and K_b is K_n = K_w / (K_a × K_b), where K_w is the ion-product constant of water (1.0 × 10^-14). Solving for K_b gives K_b = K_w / (K_n × K_a) = 1.0 × 10^-14 / (4.8 × 10⁴ × 3.0 × 10^-4) = 1.6 × 10^-6.
