What is the density of 2,5-bis(bromomethyl)-1-methoxy-4-(2-ethylhexyloxy)benzene in g/mL or g/cm^3
The purpose of this experiment is to synthesize a polymer using a Gilch polymerization of 2,5- bis(bromomethyl) - 1 -methoxy-4-(2-ethylhexyloxy) benzene, to investigate the polymer's photophysical properties, and to understand the mechanism of the polymerization reaction. Introduction Poly(p-phenylene vinylenes), or PPVS, are highly luminescent polymers that are used for a variety of commercial applications. Their general structure is shown in Figure . PPVS can be synthesized via a number of routes, including a Gilch polymerization reaction, which will be used...
Benzene (C6H6) and cyclohexane (C6H12) form an ideal solution at 25°C. The density of benzene is 0.876 g/cm 3 and the density of cyclohexane is unknown.A liquid mixture is prepared by mixing 357 mL of benzene and 643 mL of cyclohexane. The vapor in equilibrium with this liquid has a mole fraction of benzene of 0.4. What is the density of cyclohexane in units of g/cm3? Data: Vapor pressure of benzene = 99 mmHg, at 25°C Vapor pressure of cyclohexane...

Part C Iron has a density of 7.86 g/cm (1 cm = 1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 4.25 kg . Note that the density is provided in different units of volume and mass than the desired units of volume (dL) and the given units of mass (kg). You will need to express the density in kg/dL (1 cm = 1 mL) before calculating the volume for the piece of...
