Your answer is he rms speed is 586 m/s. The equation for rms speed is rms_speed = sqrt((3*gas constant*temperature_in_Kelvin)/molar mass). The gas constant is 8.31 kgm^2/(s^2Kmol) and molar mass is 0.028Kg/mol. Convert Celsius to Kelvin => 386K and plug in the numbers. Rms_speed = sqrt((3*8.31*386)/0.028) = 586m/s.
