If he(g) has an average kinetic energy of 8750 j/mol under certain conditions, what is the root mean square speed of cl2(g) molecules under the same conditions?

18.74 m/s is the root mean square speed of chlorine gas molecules under the same conditions.

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

where,

K.E = Average kinetic energy

=Universal gas constant =8.314 J /mol K

T = Temperature of the system

He has an average kinetic energy of 8750 J/mol

T =

T = 701.63 K

The formula used for root mean square speed is:

where,

= root mean square speed

k = Boltzmann’s constant =

T = temperature =701.63 K

M = atomic mass = 0.071 kg/mole

= Avogadro’s number =

18.74 m/s is the root mean square speed of chlorine gas molecules under the same conditions.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
