Consider a mixture of hydrocarbons that consists of 60 percent (by volume) methane, 30 percent ethane, and 10 percent propane. After passing through a separator, the mole fraction of the propane is reduced to 1 percent. the mixture pressure before and after the separation is 100 kPa. Determine the change in the partial pressures of all the constituents in the mixture.

Explanation:

mole fraction of propane after passing through the separator is

mole fractions of ethane and methane after passing through separator are:

Change in partial pressures then can be written as:

 where and are mole fractions after and before passing through the separator

Hence,

answer:

make you upset

explanation:

answer:

the average distance would be 20ly

Explanation:

100,000ly times 5,000ly=20ly
