Compute the root-mean-square speed of H2 molecules in a sample of hydrogengas at a temperature of 169°C.
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...
