A sealed container contains 8 moles of radon gas at stp, Ask an Expert

Academics

A sealed container contains 8 moles of radon gas at STP. Estimate the number of radon atoms having speeds in the range from 227.0 m/s and 229.0 m/s. (Hint: Assume the probability of radon atoms having speeds between 227.0 m/s and 229.0 m/s is constant. Assume STP is 1 atm, and 273.15 Kelvin. )?
