Calculating the root mean square speed
« on: September 15, 2009, 03:20:00 PM »
I do not understand the following question:

Calculate the root mean square speed, Urms, in m/s at 227degreesC and 900 torr of a gas having a molecular weight of 16.0g/mol.

Answer: 833 m/s

Any help would be greatly appreciated!
Thanks in advance!
