In acetic acid vapor, the molecules exist as monomers and others as dimers. If the density of the vapor at 76.85 ° C and 1 atm is 3.23 g / L, what is the percentage of molecules?
that form dimers?
to. 54.3%
B. 26.4%
C. 14.7%
D. 5.6%

the answer is option a.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
