The solution containing 4.0 g of PVC in one litre of dioxane was found to have O.P. of 6.0 × 10−4 atm. at 300 K. The mol. mass of polymer is
(A) 6.4 × 102
(B) 3.0 × 102
(C) 1.6 × 105
(D) 5.6 × 104
W2 = 4g
V = 1000 mL = 11
= 6.0 × 10−4 atm
T = 300 K
R = 0.0821 It atm K−1 mol−1
M2V = W2RT
= 16.42 × 104
M2 = 1.6 × 105
