Question

Cinnamic acid and urea melt at 133degree C. The melting point of an unknown is found to be 133 degree C. What experiments using melting range determinations could be done to determine if the unknown is cinnamic acid or urea? A 15.00 g metal sphere was found to have a diameter of 1.85 cm. The volume of a sphere is V = (4/3)pir^3 Calculate the density of the sphere and assuming that the sphere is made out of one of the elements, aluminum, chromium, iron, lead, titanium or zinc, determine its composition. A 55.81 gram irregular object made out of one of the metals in #6 raises the water level in

Explanation / Answer

You may add different mixes of urea - solute vs. cinnamic acid - solute.

The difference (melting point difference) will help to determinate different properties, specially molality of each; that is, mol per kg of solvent
