Hello! these are physics problems can you please solve before 5:30pm

One assumption of the ideal gas law is that the atoms or molecules themselves occupy a negligible volume. Verify that this assumption is reasonable by considering gaseous xenon (Xe). Xenon has an atomic radius of 2.0 x 1071% m. For STP conditions, calculate the percentage of the total volume occupied by the atoms. Express your answer as a percentage with no units. e [ | Four tanks A, B, C, and D are filled with monatomic ideal gases. For each tank, the mass of an individual atom and the rms speed of the atoms are expressed in terms of m and Vrms respectively (see the table). Suppose that m = 2.23 x 10-26 kg, and Vrms = 1150 m/s. Find the temperature of the gas in each tank.

The mass per mole of Cl,is 70.9 g/mol. (a) Determine the volume of the tank. (b) Later, the temperature of the tank has dropped to 25 C and, due to a leak, the pressure has dropped to 3.20 x 10 Pa. How many grams of chlorine gas have leaked out of the tank? (a) Number n Units v (b) Number n Units v Insects do not have lungs as we do, nor do they breathe through their mouths. Instead, they have a system of tiny tubes, called tracheae, through which oxygen diffuses into their bodies. The tracheae begin at the surface of the insect's body and penetrate into the interior. Suppose that a tracheae is 1.63 mm long with a cross-sectional area of 1.19 x 10"m2. The concentration of oxygen in the air outside the insect is 0.791 kg/m?, and the diffusion constant is 1.90 x 10> m?/s. If the mass per second of oxygen is diffusing through a tracheais 1.52 x 10712 kg/s, then find the oxygen concentration at the interior end of the tube
