Question

4.0 g of argon in a bulb at a temperature of T K has a pressure P atm . When the bulb was placed in water bath at a temperature 5 0 ∘ C more than the first one, 0.8 g of gas had to be removed to get the original pressure. T is equal to

PV = M W ​ RT At constant pressure and volume, the above equation reduces to: w 1 ​ T 1 ​ = w 2 ​ T 2 ​ 4 × T = 3.2 × ( T + 50 ) 0.8 T = 160 T = 0.8 160 ​ = 200 K
