5.(16 pts, 8min) Do either (a) or (b) (a) A sample of Ar(g) having a mass of 0.0166 g is collected over water. If the temperature and total pressure of the system are 48.0°C and 676 mmHg respectively, what is the volume of the gas expressed in liters? Data: is 83.71 mmHg. R= 0.0821 L atm/(K mol), 1 atm 760 mmHg Atomic mass of Ar-39.95 and the vapor pressure of water at 48.0°C (b) Consider the following reaction: 2 NAOH(aq)+2...

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...
The first two problems are to be submitted today. 1.(25PTS) At midday on the lunar surface, a temperature of 98 95°C was recorded Calculate the average speed of Neg) in m/s and mile/hr under these conditions. The formula for the average speed can be derived from the kinetic theory of gases and it is given by SRT average_speed= (molar mass) 2. (25PTS) Data: R -0,0821 L atm/K mole) -8.314 JAK mole). Atomic mass Ne-20.18 A reaction that can be used...
