1.	What is the specific gravity of CO at 27^oC and pressure 5 atm with respect to air (molecular wt. = 29 g) at 27^oC and pressure 10 atm?(a) 0.48(b) 0.56(c) 0.64(d) 0.72This question was addressed to me in an interview.The query is from Ideal Gas Law topic in chapter Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering
Answer» Right option is (a) 0.48 Best EXPLANATION: Density of CO = 528/(0.0821300) = 5.68 g/L, density of AIR = 1029/(0.0821300) = 11.77 g/L, => SPECIFIC gravity = 5.68/11.77 = 0.48.
