If root mean square velocity of the molecules of hydrogen at NTP is 1840 m/sec, calculate the root mean square velocity of oxygen molecules at NTP?

really easy one.... from the formula we can infer that at same conditions vel is inversely proportional to molecular mass so now you can do x/1840=2/32 that makes x=115m/s right dude
