At what temperature is the root-mean-square speed of nitrogen molecules equal to the root-mean-square speed of hydrogen molecules at 46 oC? (Hint: The molar mass of hydrogen atoms is 1.008 g/mol and of nitrogen atoms is 14.007 g/mol. The molar mass of H2 is twice the molar mass of hydrogen atoms, and similarly for N2.) The answer is in degree C.

VI.(15pts) The following picture shows a gas entrapped in a sealed syringe with a movable plunger: (a)(7 pts) If the trapped gas is a hydrocarbon with empirical formula CH, and if the gas has a volume of 5.58 ml and a mass of 8.98mg at 45.0°C,...
Q9. Which of the following gases has the slowest Root-Mean-Square Speed (rms) at a temperature of 25 °C? (R = 8.314 kg. m2 / (52. K.mol)] a) CO2 b) NO2 c) H2S d) SO2 e) Cl2
EXAMPLE 6-14 Calculating a Root-Mean-Square Speed Which is the greater speed, that of a bullet fired from a high-powered M-16 rifle (2180 mi/h) or the root-mean-square speed of H2 molecules at 25 °C? Analyze This is a straightforward application of equation (6.19). We must use SI units: R = 8.3145JK mol- and M = 2.016 X 10-kg mol-1. Recall that 1 J = 1 kg m?s Solve Determine urms of H2 with equation (6.19). 3 x 8.3145 kg m’s 2...
