Question
At what temperature (in kelvin) would the rms speed of oxygen molecules (molar mass 32 g/mol) equal the rms speed of hydrogen molecules (molar mass 2 g/mol) at 300 K?
✓ Verified answer: 4800checked by our engine — not a guess
Step-by-step solution
v_rms = sqrt(3RT/M). Equal rms speeds require T/M equal: T_O2/32 = 300/2.
T_O2 = 300*32/2 = 4800 K.
Final answer4800.0
