- A sample of pure iron has a mass of 13.8 g. Calculate the number of moles in the sample and iron atoms in the sample. (a) moles in the sample moles (b) iron atoms in the sample atomsQuestion 5, Physics - equation sheet attachedThere are two important isotopes of uranium, 235 U and 238 U ; these isotopes are nearly identical chemically but have different atomic masses. Only 235 U is very useful in nuclear reactors. Separating the isotopes is called uranium enrichment (and is often in the news as of this writing, because of concerns that some countries are enriching uranium with the goal of making nuclear weapons.) One of the techniques for enrichment, gas diffusion, is based on the different molecular speeds of uranium hexafluoride gas, UF6 . (a) The molar masses of 235 U and 238 UF6 are 349.0 g/mol and 352.0 g/mol, respectively. What is the ratio of their typical speeds vrms ? (b) At what temperature would their typical speeds differ by1.00 m/s? (c) Do your answers in this problem imply that this technique may be difficult?

- A sample of argon gas is in a container at 35.0° C and 1.22 atm pressure. The radius of an argon atom (assumed spherical) is 0.710 x 10-10 m. calculate the available volume for each atom.True/False The particle transport loss due to diffusion in a circular tube is dependent on tube diameter and particle diffusivity.A Geiger-Muller tube is a type of gas-filled radiation detector. It can detect particles like X-rays, alpha particles, and beta rays (electrons). This is useful in quantizing the activity of a radioactive source or determining if an area containing radioactive material is safe to enter. If a Geiger counter is filled with 1 mol of argon gas at pressure P = 1.0620 × 10ª Pa and temperature T = 20.0 °C, what is the density p of the gas in this Geiger tube in grams per cubic centimeter? The atomic mass of argon is aa, = 39.948 g/mol. g/cm3
