(a) If you toss 10 coins, what percent of the time will you get the three most likely macrostates (6 heads and 4 tails, 5 heads and 5 tails, 4 heads and 6 tails)? (b) You can realistically toss 10 coins and count the number of heads andtails about twice a minute. At that rate, how long will it take on average to get either 10 heads and 0 tails or 0 heads and 10 tails?
(a) Calculate the volume occupied by 1.00 mol of an ideal gas at a pressure of 1.00 atm (1.01 · 10^5
N/m^2 ) and temperature 0°C (273 K). (b) How many molecules are there per cubic centimater at these
conditions? (This is called the Loschmidt number.)
At what height is the atmospheric pressure 29.0% of what it is at sea level? Assume
the molar mass of the air molecules to be 29.0 g/mol and that the air temperature is
uniformly 287 K.
