🤓 Based on our data, we think this question is relevant for Professor Brunold's class at UW-MADISON.
1 g = 1x10-3 kg/mol
MM of F2 : 19.0 (2) = 38 g/mol or 38x10-3 kg/mol
MM of Cl2 : 35.45 (2) = 70.90 g/mol or 70.90x10-3 kg/mol
MM of Br2 : 79.90 (2) = 159.8 g/mol or 159.8x10-3 kg/mol
Calculate the root mean square velocity of F2,Cl2, and Br2 at 302 K .
