Molecular weight calculation: 12.0107*6 + 1.00794*6 Convert grams C6H6 to moles or moles C6H6 to grams. ››More information on molar mass and 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? chem. Benzene causes central nervous system damage acutely and bone marrow damage chronically and is carcinogenic. What is the molar mass of an unknown compound? Molar mass of C6H6 = 78.11184 g/mol This compound is also known as Benzene.. benzene: C6H6. 2 C 6 H 6 (l) + 15 O 2 (g) → 12 CO 2 (g) + 6 H 2 O(g) ΔH° rxn = -6278 kJ 18. Benzene is less dense than water and is slightly soluble in water.Hence it floats on water.Benzene vapor is heavier than air. and freezing point of pure benzene is 5.5 °C) 17. Analysis shows the compound to be 7.74% H by mass. 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 … 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. Instant Molecular Weight For Over 100 Million Compounds. 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 . Benzene C6H6 Molar Mass, Molecular Weight. (Note K for benzene = 5.12°C/m. So I assumed 100 g. 7.74% => 7.74 g H. 78.1-7.74= 70.36 g C (Do not use the molar mass of the compound to find the empirical formula!) ››C6H6 molecular weight.
