For the gas constant, use R = 8.314 J/mol-K For Avogadro's number, use N_0 = 6.022 times 10^23 molecules. Be careful of units! All the conversions you need are in the information section of the lab. Suppose the volume of the syringe is 47.5 cc. You measure the pressure as 1.58 atm, and the temperature as 19.8 degree C. Assume: the diameter of the plunger on the syringe is 1.44 cm. Find the number of moles of gas in the...

Sodium dimer, Na2, has a vibrational constant we of only 159 cm, whereas for H2 we = 4401 cm1. If a sample of Na2 at 301 K has the same energy and number of moles as a sample of H2, use the equipartition principle to estimate the temperature of the H2 sample. Both sampless are in the gas phase. Express your answer to three significant figures and include the appropriate units. HA T Na2 Value Units Request Answer Submit
