Solve the following problem:
1 .The molar mass of iodine is 127 g. A standing wave in iodine vapor at 400 K produces nodes that are 6.77 cm apart when the frequency is 1000 Hz. Is iodine vapor monatomic or diatomic?
2. The root-mean-square speed Wrms is defined as √(w)2 . show that
a. Wrms = √3kT/m .
b. Wrms = √3/γ times the speed of sound.
