An atom of bromine has a mass about four times greater than that of an atom of neon. Which choice makes the correct comparison of the relative numbers of bromine and neon atoms in 1,000 g of each element? An unknown compound with a molar mass of 155.06 g/mol consists of 46.47% C, 7.80% H, and 45.72% CI. Find the molecular formula for the compound.
2. For a monatomic gas, one measure of the "average speed" of the atoms as the root mean square speed, 93 ns -(3k,/m, in which m is the molecular mass and k is the Boltzmann constant. Using this formula, calculate the de Broglie wavelength for Ar at 200K and at 900K.

A gas of helium atoms (each of mass 6.65×10−27kg) is at room temperature of 7.1°C. What is the de Broglie wavelength of the helium atoms that are moving at the root-mean-square speed?
Five samples of neon gas are described in the table below. Rank the samples in order of increasing average kinetic energy of the atoms in them. That is, select "1" next to the sample in which the neon atoms have the lowest average kinetic energy. Select "2" next to the sample in which the neon atoms have the next lowest average kinetic energy, and so on. sample average kinetic energy of atoms in sample amount pressure temperature -28 °C 1.2...
