Question #c3fe6

Answer 1

use the formula `sqrt((3RT)/M)`

Explanation:

root mean square speed of any molecule/atom can be found by using formula : `sqrt( (3RT)/M )` where R is the universal gas constant , T is the temperature in kelvin and M is mass of the molecule/atom in kg.
thus , rms speed of hydrogen atom is = `sqrt ( (3*8.314*900)/(1*10^-3) )`
= `4737.91 ms^-1`
