Answer:
The gas was Hexane
Explanation:
taking the diference between the mass of the flask and the final mass qe can calculate the mass of liquid injected (assuming none escaped the flask):
with the volume of the flask we can get the density of the gas at the indicated pressure and temperature:
From the ideal gases law we have that the density can be calculated as:
Where R is the ideal gases constant = , and M the molecular weight of the fluid. Solving for M:
Note that the temperature is computed in Kelvin T= 18+273=291K
The gas with the closer molar mass is Hexane
