p-dichlorobenzene is an organic molecular (covalent) compound with i = 1 and Kf = 7.10 oC/m A student weighed 11.20 mL of p-dichlorobenzene and recorded mass of it as 10.820 g. The freezing point of the pure p-dichlorobenzene liquid was determined as 53.1 oC. 1.118 g of an unknown solid compound was added and completely dissolved in the previous sample of pure p-dichlorobenzene liquid. The freezing point determination procedure was conducted for the solution and the freezing point of this...
what is the structure formula and what is molecular weight and
is there a hydrogen bond for the substance in the table
Substance Formula Structural Formulas Molecular Weight Hydrogen Bond (Yes or No) Ethanol C2H5OH 1-propanol C3H OH 1-butanol C4H4OH n-pentane C5H12 methanol CH OH n-hexane C6H14 Acetone CH3COCH3
Fill in the following information for Adipic Acid: molecular weight, g or ml, mole, melting point, boiling point, and density. Example. 3-phenyl-1-propanol MW: 136.19, g or mL: 0.20g, mole: 0.0015, MP: -18, BP: 235, density: 1.008. Can someone please SHOW how to get g/mL for Adipic Acid, someone on Chegg wrote 0.5g , but how is it 0.5g, as well as filling it in?? And can you also explain why 3-phenyl-1-propanol is 0.20g. Thank you
You may have noticed that % composition vs Melting Point graphs are given in % Mole not 96 Weight. This is because melting point depression is a colligative property (review in your general chemistry text) that depends on the moles of impurity, the same number of moles of impurity of two different compounds will cause the same melting point depression! Before the advent of mass spectrometry this was one of the techniques used to determine the molecular weight of compounds....
