Λ? = K * 1000 / M = (2 * 10? * 10³) / 10? ³ = 20 Scm²mole? ¹
For weak acid (α) = Λ? / Λ? = 20 / 190 = 2/19
K? = Cα² / (1 - α) = 10? ³ * (2/19)² / (1 - 2/19)
= 10? ³ * (4/361) / (17/19) = 0.01238 * 10? ³
= 12.38 * 10?
So, ans is 12 (the nearest integer).

% of N = (1.4 * Normality of acid * volume of acid used) / (mass of organic compound)
42 = (1.4 * (1 * 2) * volume of acid used) / 0.8
Volume of acid used = (42 * 0.8) / (1.4 * 2) ml

q = +150 J
w = -200 J
∴ ΔU = q + w = 150 - 200 = -50 J
So, magnitude of ΔU is 50 J.
