The density of O 2 is 16 at NTP. At what temperature(in o C) its density will be 14? Consider that the pressure remains constant.

Correct answer

39

Step-by-step solution

As d = P M R T d 1 T 1 = d 2 T 2 When p remains constant d 1 = 16 ; d 2 = 14 ; T 1 = 273 K , T 2 = ? d 1 T 1 = d 2 T 2 16 × 273 = 14 × T 2 T 2 = 312 K T 2 = 312 - 273 = 39 ℃
