Two flasks of equal volumes have been joined by a narrow tube of negligible volume. Initially both the flasks are 300 K and totally 9 mole of gas is present. One of the flasks is then placed in a thermostat at 600K. How many moles of gas is present in hot bulb.

1.	Two flasks of equal volumes have been joined by a narrow tube of negligible volume. Initially both the flasks are 300 K and totally 9 mole of gas is present. One of the flasks is then placed in a thermostat at 600K. How many moles of gas is present in hot bulb.
Answer» Solution :TOTAL initial MOLES = total final moles `(n_("hot"))/(n_("cold")) = ((PxxV)/(R XX 600))/(P xx V//R xx 300) = 1/2` `n_("hot") = 1/3 xx 9 = 3 `moles.
