The van der Waals coefficients of monatomic Krypton gas are a = 0.2318 m6 Pa/mol² and 6 = 39.78 × 10-6 m³/mol. Calculate the + ontholou fthin

Answer part a and b

I only need help with part b

5.69 You want to store 165 g of CO2 gas in a 12.5-L tank at room temperature (25°C). Calculate the pressure the gas would have using (a) the ideal gas law and (b) the van der Waals equation. (For CO2, a = 3.59 atm L^2/mol^2 and b = 0.0427 L/mol.)

What are the units of a? What are the units of b? For carbon dioxide the numerical value of a is 3.592 and the numerical value of b is 0.0429. atm Use the van der Waals equation to calculate the pressure of a sample of carbon dioxide at 55.0 °C with a molar volume of 0.515 L/mol. Round your answer to 3 significant digits. Use the Ideal Gas Law to calculate the pressure of the same sample under the same conditions. Round this answer to 3 significant digits also. atm Explanation Check

Calculate the most probable speed of oxygen (O2) molecules in a gas at T = 334 K,   O2 atomic mass is 32 amu, where the atomic mass unit (amu) is 1.66 x 10-27 kg. Provide your answer in units of meters per second, but do not include the units in your answer, just the number in normal form to 3 significant digits

A 2.61 gram sample of a solid mixture contains NaClO3 as well as unreactive material. When heated, only the NaClO3 in the mixture decomposes to produce 992 milliliters of O2 gas at 225◦C and 772 mmHg according to the unbalanced equation NaClO3(s) −→ NaCl(s) + O2(g). What is the percent by mass of NaClO3 in the mixture?

The van der Waals equation of state was designed (by Dutch physicist Johannes van der Waals) to predict the relationship between pressure p, volume V and temperature T for gases better than the Ideal Gas Law does: p+a n #2²7) (V- (V-nb)=nRT The parameters a and b must be determined for each gas from experimental data. Use the van der Waals equation to answer the questions in the table below. What are the units of a? The van der Waals equation of state. R stands for the gas constant and n for moles of gas. What are the units of b? For water the numerical value of a is 5.464 and the numerical value of b is 0.0305. Use the van der Waals equation to calculate the pressure of a sample of water at 430.0 °C with a molar volume of 1.92 L/mol. Round your answer to the correct number of significant digits. Use the Ideal Gas Law to calculate the pressure of the same sample under the same conditions. Round your answer to the correct number of significant digits. 1 0 П atm atm x10 H X ロ・ロ S
