Molecular weight calculation: 12.0107*6 + 1.00794*14 ›› Percent composition by element. Hexane (/ˈhɛkseɪn/) is an organic compound, a straight-chain alkane with six carbon atoms and has the molecular formula C6H14. About n-Hexane; N-Hexane weighs 0.6606 gram per cubic centimeter or 660.6 kilogram per cubic meter, i.e. Hexane is the common name used to indicate all molecules with this formula. The molecular formula for Hexane is C6H14. The melting points are quite different and the trend is not apparent.[12]. 2005-03-26. Molar mass of C6H14 is 86.1754 g/mol Compound name is hexane Convert between C6H14 weight and moles For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. Like gasoline, hexane is highly volatile and is an explosion risk. density of n-Hexane is equal to 660.6 kg/m³; at 25°C (77°F or 298.15K) at standard atmospheric pressure. There are a number of structural isomers we can draw to match this formula but, in IUPAC nomenclature, we use hexane specifically to indicate unbranched molecule, and it is also known as n-hexane. Commercial samples of n-hexane however often contains methylcyclopentane, which features tertiary C-H bonds, which are incompatible with some radical reactions. Hexane is classified as an alkane and is composed of a chain of 6 central carbon atoms each saturated with hydrogen. No menu assigned; 0330 380 1647 [19] n-Hexane is sometimes used as a denaturant for alcohol, and as a cleaning agent in the textile, furniture, and leather industries. C3H7 C6H14 C9H21 C6H12 Question 8 The empirical formula for ethylene glycol is CH3O. 1,6-Hexanediol is prepared by the hydrogenation of adipic acid or its esters. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. Above 300 ppm, the amount of n-hexane in the body rose with increasing atmospheric concentrations from 1.6 up to a limiting value of 9.6, which corresponded to the thermodynamic distribution coefficient of n-hexane between the organism and the atmosphere. The molar mass of hexane is 62.08 grams per mole. Molar Heat Capacity (cP) of Hexane. ", https://en.wikipedia.org/w/index.php?title=Hexane&oldid=1005491070, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Articles with unsourced statements from March 2018, Creative Commons Attribution-ShareAlike License, −96 to −94 °C; −141 to −137 °F; 177 to 179 K, 68.5 to 69.1 °C; 155.2 to 156.3 °F; 341.6 to 342.2 K, This page was last edited on 7 February 2021, at 22:57. of a chemical compound, More information on (C = 12, O = 16, H = 1) a. The mass {eq}m {/eq} of oxygen required to react with 20.0 mL of liquid hexane is: Convert grams Hexane to moles  or  moles Hexane to grams, Molecular weight calculation: Create . Hexanes is cheaper than hexane and is often used in large scale operations not requiring a single isomer (e.g., as cleaning solvent or for chromatography). The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. For instance, fluorine (F) is the most electronegative element and is assigned an EN value of 4. Hit enter to search or ESC to close. N-Hexane weighs 0.6606 gram per cubic centimeter or 660.6 kilogram per cubic meter, i.e. 2,5-Hexanediol may be further oxidized to 2,5-hexanedione, which is neurotoxic and produces a polyneuropathy. Hexane is a significant constituent of gasoline. J. of Thermophysics, Vol. Using a molar heat of combustion of hexane (C6H14) - 4163 kJ/mol, the mass of hexane required to increase the temperature of 1.76 L of water from 21.0°C to 70.0°C is … 2C 6 H 14 + 19O 2 → 12CO 2 + 14H 2 O. Hexane being a higher hydrocarbons undergo thermal cracking forms more than one hydrocarbon. Higher alkanes present as impurities in hexanes have similar retention times as the solvent, meaning that fractions containing hexane will also contain these impurities. The molecule is chiral, and is one of the two isomers of heptane to have this property.The enantiomers are (R)-3-methylhexane and (S)-3-methylhexane.References This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. [citation needed]. The greater the EN value, the more that atoms of that element pull on electrons. Hexane is a hydrocarbon compound with a chemical formula of C 6 H 14. To complete this calculation, you have to know what substance you are trying to convert. The data represent a small sub list of all available data in the Dortmund Data Bank. 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 of these products together. The exact composition of the fraction depends largely on the source of the oil (crude or reformed) and the constraints of the refining. Heat of Vaporization of Hexane. They are commonly used in food based soybean oil extraction in the United States, and are potentially present as contaminants in all soy food products in which the technique is used; the lack of regulation by the FDA of this contaminant is a matter of some controversy.
