(b) Using the Crystallographer's
formula to determine the density (in g/cm³) of Po:
ρ = Σ Ζ * Μ
Vell* N
You must know that a primitive cubic cell has Z = 1
Since Po is a metal, the value of "i" = 1, since it's the only entity!
MM of Po= 208.998 g/mol
Vcell (in cm³) = a³
Vcell (3.36 x 10-8 cm)³ = 3.793 x 10-23 cm³
N = 6.022 x 1023 atoms/mol
Thus: p = (1 atom/cell) (208.998 g/mol) = 9.16 g/cm³
(3.793 x 10-23 cm³) (6.022 x 1023)
(a) How do the viscosity and surface tension of liquids change as intermolecular forces become stronger? (b) How do the viscosity and surface tension of liquids change as temperature increases? Accounts for these trends
(a) What is the relationship between surface tension andtemperature? (b) What is the relationship between viscosityand temperature? (c) Why do substances with high surfacetension also tend to have high viscosities?
