# benzene molar mass

2 C 6 H 6 (l) + 15 O 2 (g) → 12 CO 2 (g) + 6 H 2 O(g) ΔH° rxn = -6278 kJ 18. Instant Molecular Weight For Over 100 Million Compounds. So I assumed 100 g. 7.74% => 7.74 g H. 78.1-7.74= 70.36 g C The freezing point of the solution is found to be 2.8 degrees C. The freezing point depression constant for benzene is 4.3 degrees C/m. ››More information on molar mass and molecular weight. The molecular weight of chemical compounds is one of the basic information for research and development, which are frequently available only at a specific chemical-related website when the compound is not popular. The air has a specific molar heat capacity of 29.1 j/mol*K. The molar mass of air is 28.9 and a density . and freezing point of pure benzene is 5.5 °C) The freezing point of this solution is 1.02°C below that of pure benzene. Molecular weight calculation: 12.0107*6 + 1.00794*6 Benzene C6H6 Molar Mass, Molecular Weight. Benzene causes central nervous system damage acutely and bone marrow damage chronically and is carcinogenic. Benzene is less dense than water and is slightly soluble in water.Hence it floats on water.Benzene vapor is heavier than air. If 9.56-gram sample of this compound is dissolved in 250 grams of benzene. What volume of benzene (C 6 H 6, d= 0.88 g/mL, molar mass = 78.11 g/mol) is required to produce 1.5 x 10 3 kJ of heat according to the following reaction? Find the empirical and molecular formulas of benzene. Benzene, C6H6, is a clear colorless to light-yellow liquid, flammable with a petroleum-like, aromatic odor. Molar mass of C6H6 = 78.11184 g/mol This compound is also known as Benzene.. Temperature (K) A B C Reference Comment; 333.4 - 373.5: 4.72583: 1660.652-1.461: Eon, Pommier, et al., 1971: Coefficents calculated by NIST from author's data. (Do not use the molar mass of the compound to find the empirical formula!) Convert grams C6H6 to moles or moles C6H6 to grams. Benzene contains only carbon and hydrogen and has a molar mass of 78.1 g/mol. chem. ››C6H6 molecular weight. Calculate the molar mass of a compound from the following information. Analysis shows the compound to be 7.74% H by mass. • C6H6 + Br2 = C6H5Br + HBr What volume of benzene (C6H6,d=0.88g/ml,molar mass=78.11g/mol) is required to produce 1.5 x 10^3 kJ of heat according to the following reaction? Gas chromatography-mass spectrometry identified 1,2-diacetylbenzene in the urine samples of rats given 165 mg kg-1 1,2-diethylbenzene orally on four consecutive days. What is the molar mass of an unknown compound? (Note K for benzene = 5.12°C/m. You find that the freezing point of benzene is 5.5 degrees C. You then dissolve 1.60 grams of the unknown compound in 20.00 grams of benzene. benzene: C6H6. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all … chemistry 17.
