It does not readily evaporate at room temperature. Aniline is slightly soluble in water and mixes readily with most organic solvents. Aniline is used to make a wide variety of products such as polyurethane foam agricultural chemicals synthetic dyes antioxidants stabilizers for the rubber industry herbicides.
Molar mass and percent composition worksheet. Determine the molecular formula for a compound with the empirical formula NPCl 2 and a molar mass of 347. Molar Mass and Percentage Composition Calculate the molar masses and percentage composition of each of the following compounds.
Calculate the percent composition of carbon for. The atomic mass of hydrogen is 100794 amu and that of oxygen is 159994. Since water molecules contain 2 hydrogen atoms and only one oxygen atom the molecular mass of H 2 O is 180154 amu.
The molar mass of a substance is defined as the total mass of one mole of the substance. It is often represented in terms of grams per mole. Couplingcomplexing with 2-amino-4-nitrophenol and 24-dimethoxy aniline.
The optical reduced scattering coefficient and mass density distribution factor analysis. These markers were combined utilizing logistic regression and the combined rectal LEBS marker had a sensitivity of 88 and specificity of 72 for advanced adenomas. The rectal LEBS was not confounded by location of the adenomas.

A simplified version of the isolated vascularly perfused rat small intestine was developed. With 13-dinitrobenzene 13-DNB as a model xenobiotic.
Both 3-nitroaniline 3-NA and 3-nitroacetanilide 3-NAA were formed and absorbed following intralumenal doses of 13-DNB 18 or 42 umol to isolated vascularly perfused rat small intestine. Dose fasting or antibiotic pretreatment had no. 11 g of aniline monomer with 01 g of SDS and 01 g of CoFe 2 O 4 nanoparticles were dissolved in 10 ml of distilled water and the solution was stirred for 30 min on magnetic stirrer to foam up strongly.
The resulting solution was then placed in an ice bath until the temperature was reached to 04 C. Also 228 g of ammonium persulfate APS with a molar mass of 22818 g. Must show ratio of massmolar mass for both elements in calculations PV nRT.

An empirical equation was developed which gives net heat of combustion based on the determined values of aniline point ASTM D 611 and API gravity ASTM D 287. If the fuel contains sulfur a correction is applied for sulfur determined according to ASTM D129 D 1266 D 2622 or D 3120 the method selected depends on the volatility of the sample. This can be converted to kJ per mass units.
