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. Benzene C6H6 Molar Mass, Molecular Weight. 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? 17. 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 . chemistry Benzene contains only carbon and hydrogen and has a molar mass of 78.1 g/mol. ››More information on molar mass and molecular weight. and freezing point of pure benzene is 5.5 °C) Find the empirical and molecular formulas of benzene. The freezing point of this solution is 1.02°C below that of pure benzene. 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. 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. 2 C 6 H 6 (l) + 15 O 2 (g) → 12 CO 2 (g) + 6 H 2 O(g) ΔH° rxn = -6278 kJ 18. If 9.56-gram sample of this compound is dissolved in 250 grams of benzene. 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. • C6H6 + Br2 = C6H5Br + HBr What is the molar mass of an unknown compound? Benzene is less dense than water and is slightly soluble in water.Hence it floats on water.Benzene vapor is heavier than air. Convert grams C6H6 to moles or moles C6H6 to grams. Molecular weight calculation: 12.0107*6 + 1.00794*6 Benzene, C6H6, is a clear colorless to light-yellow liquid, flammable with a petroleum-like, aromatic odor. 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 … 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? Benzene causes central nervous system damage acutely and bone marrow damage chronically and is carcinogenic. So I assumed 100 g. 7.74% => 7.74 g H. 78.1-7.74= 70.36 g C 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. Molar mass of C6H6 = 78.11184 g/mol This compound is also known as Benzene.. (Note K for benzene = 5.12°C/m. Analysis shows the compound to be 7.74% H by mass. (Do not use the molar mass of the compound to find the empirical formula!) ››C6H6 molecular weight. chem. benzene: C6H6. Weight calculation: 12.0107 * 6 + 1.00794 * 6 + 1.00794 * +!
