Aclosed vessel system of volume 2.5 l contains a mixture of neon and fluorine. the total pressure is 3.32 atm at 0.0°c. when the mixture is heated to 15°c, the entropy of the mixture increases by 0.345 j/k. what amount (in moles) of each substance (ne and f2) is present in the mixture? (heat capacity of monoatomic gas = 3/2r and that for a diatomic gas = 5/2r)
