(4) ab22 gm: of CO2 at 27° C is mixed with 16 gm. of O,at 37C. The temperature of the mixture is:-(1)31.16°C(3) 37°C42.(2) 27° C(4)30° C

Answer»

No of moles of CO2= mass/molar mass = 22/44= 0.5 mole

No of moles of O2= 16/32 = 0.5 mole

Since both have same no. of moles, the resulting temperature will be the average of both their temperatures.

...The temperature of the mixture is = (27+37)/2 =32oC
