Question

suppose a sealed 27m3 tank is filled with 6000 moles of Chlorine gas at an initial pressure of 206 kPa. what is the temperature? The gas constant is R=8.314 J/(mol-1x k)

Answer 1

According to ideal gas equation: pressure X volume = no. of moles X gas constant X Temperature …..(1)

it is given in the question that , pressure of the gas = 206 KPa = 206000 Pa volume of gas = 27 m3 no. of moles of the gas =6000    value of gas constant = 8.314J/(mol-1x k)

let temperature of gas be 'T' kelvins

putting value of these in equation (1) we get    206000 X 27 = 6000 X 8.314 X T

solving this we get T= 111.49 kelvins

so temperature is 111.49 kelvins
