- Its not a mixture because mixture is Just dispersed of diferrent elements or a compound which are not in fix ratio
There is a typo in the question. hopefully, i assumed the correct number.
when volume and temperature are given, that means you need Charles' law. remember that with any gas formula, the temperature has to be in Kelvin which can be determined by simply adding 273 to Celsius.
Charles' law---> V1/T1 = V2/T2
V1= 2.8 m3
T1= 20 C = 293 K
V2= 0.2 m3
T2= ????
let's plug in the values
2.8/ 293 = 0.2/ T2
T2= 20.9 Kelvin
to change the answer to Celsius, just subtract 273 to the temperature
20.9 - 273= -252 Celsius
