Solution:The combustion reactions for propane and butane are: (a) Stoichiometric Air RequirementOn the basis of 1 volume of the fuel gas, the propane content requires0.7 Ã (5 + 18.8) = 16.7 vols airand the butane requires0.3 Ã (6.5 + 24.5) = 6.3 vols airHence the stoichiometric air-to-fuel ratio is 23:1.

If you get the small it will likely cling to your torso so if you tend to wear close fitting tops then go for the small.Viscose does not shrink so getting a large could backfire in that throwing it in the wash wont make it any smaller. Good luck.Source(s): I am from a family of seamstresses.f you get the small it will likely cling to your torso so if you tend to wear close fitting tops then go for the small.

From Wikipedia, the free encyclopedia. Viscose is both a semi-synthetic fabric formerly called viscose rayon or rayon and a solution of cellulose xanthate produced by treating dissolving pulp with aqueous sodium hydroxide and carbon disulfide used to spin the viscose rayon fiber.iscose rayon fiber is a soft fiber commonly used in dresses, linings, shirts, shorts, coats, jackets, and other outer wear; it is also used in industrial yarns (tyre cord), upholstery and carpets. It is also used in the casting of Cellophane.
