A cylinder containing CH, CH, and N, has to be prepared containing a CH, to C,H, mole ratio of 1.5 to 1. Available to prepare the mixture are (1) a cylin- der containing a mixture of 80% N, and 20% CH,, (2) a cylinder containing a mix- ture of 90% N, and 10% C,Hg, and (3) a cylinder containing pure N. What is the number of degrees of freedom, i.c., the number of independent specifications that must be made, so that you can determine the respective contributions from eac cylinder to get the desired composition in the cylinder with the three components?

Question
A cylinder containing CH, CH. and N2 has to be prepared containing a
CH, to C,H, mole ratio of 1.5 to 1. Available to prepare the mixture are (1) a cylin-
der containing a mixture of 80% N, and 20% CH. (2) a cylinder containing a mix-
ture of 90% N, and 10% C,H, and (3) a cylinder containing pure N. What is the
number of degrees of freedom, i.c., the number of independent specifications that
must be made, so that you can determine the respective contributions from eac
cylinder to get the desired composition in the cylinder with the three components?
