Question 90 of 188

The van der Waal's constant 'b' for N2 and H2 has the values 0.039 lit moil–1 and 0.0266 lit mo1–1. The density of solid N2 is 1 g cm–3. Assuming the molecules in the solids to be close packed with the same percentage void, the density of solid H2 would be (in g cm–3)

(1) 0.114

(2) 0.682

(3) 1.466

(4) 0.071
