Substance Argon (Ar) Benzene (C6H6) Ethanol (C2HSOH) Water (H20) Methane (CH4) AHyap(kl/mol) 6.3 31.0 39.3 40.8 9.2 A) Argon B) Benzene C) Ethanol D) Water E) Methane 2) (1 pt) Which of the following represents the largest volume? a) 10' nl. b) 10' pL e) 10' dl d) 10"' ml. e) 10 cl. 3) (1 pt) Which of the following represents the largest distance? a) 10' nm b) 10 pm ) 10dm d) 10 mm e) 10 cm 4) (1 p) How many cubic decimeters equals one cubic centimeter? a) 10 b) 10 e) 102 d) 10 e) 10

Explanation / Answer

1) Greater the value of delta Hvap , stronger are the intermolecular forces.Thus, the correct option is :- (D) water

2) 105 nL = 10-4 litres ; 103 pL = 10-9 litres ; 10-4 dL = 10-5 litres ; 10-3 ml = 10-6 litres ; 10-4 cL = 10-6 litres

Thus, the largest volume is :- (a) 105 nL

3) 108 pm is the largest distance

4) 1 dm3 = 1 litres

1 litres = 1000 cm3

thus, 1 dm3 = 1000 cm3

or, 1 cm3 = 10-3 dm3

Thus, the correct option is :- (b)
