What is the 'Energy per degree of freedom' of a gas particle at temperature 276K? State the answer in [eV] units. Make sure you state the answer in the units specified. Canvas is not able to accept scientific notation at this point for numerical inputs. This means you need to enter numbers like 2.34E-3 as 0.00234. 5.71E-21

ere's the second problem. You are doing an experiment in a laboratory that is 30.ºC and 1.080 atm of pressure. You take a 0.240L flask that weighs 98.005g and fill it with CO₂. After it is filled it weighs 98.206g. Calculate the molar volume of the CO₂! VSTP = P₁V₁T STP T1PSTP 1.080 * 0.240* 273 303*1 = 0.233L 1.200 * 0.240 = 0.2889 0.4899 98-206-98-005 +0.288 = 0.4 0.489/44.81 = 0.0111mol.com 0-233/0.0111 = 20.99 L/mol Mass of air = (density of air)(volume of flask) 1.200 * 0.240 = 0. 0.2889 Mass of CO₂ = (Mass of flask filled with CO₂) - (Mass of empty flask) + (Mass of air) 92-206-98·005 +0.288 = 0 0.4899

Suppose the temperature of a sample of ammonia gas is raised from -24.0 °C to 21.0 °C, and at the same time the pressure is changed. If the initial pressure was 5.6 atm and the volume increased by 30.0%, what is the final pressure? Round your answer to the correct number of significant digits.
