Explanation The root mean square velocity is given by u rms = 3 R T M Where, R is universal gas constant and M is molar mass. M o l a r m a s s o f I 2 = A t o m i c m a s s o f I × 2 = 126.9 g / m o l × 2 = 253.8 g / m o l = 0.2538 k g / m o l Substitute, R = 8 .314 J/mol/K , T = 373 K , and M = 0 .2538 kg/mol in the expression of root mean square velocity to get u rms = 3 × 8.314 J ( mol K ) × 373 K 0
