What is the name of the molecular compound C5H12?
Pentane
What Molecular has five carbon?
Pentane. Isopentenyl pyrophosphate.
Why does pentane has a higher density than 2-2-dimethylpropane?
Pentane is a liquid at room temperature (B.p. 36.1 °C, 308 K) and neopentane (2,2-dime-pe) is gas (B.p. 9.5 °C, 283 K) Both as gases they have the same density, because of the same molecular mass.
HOW MUCH DOES PENTANE WEIGH?
The molecular weight of pentane is approximately 72.15 grams per mole. So, one mole of pentane weighs 72.15 grams.
A 0.482 g sample of a 5-carbon hydrocarbon was completely vaporized at 101 C What is the molar mass of this hydrocarbon What is the molecular formula of this 5-carbon hydrocarbon?
The molar mass of the hydrocarbon is 58 g/mol. To calculate the molar mass, we use the formula: molar mass = mass / moles. Since the hydrocarbon has 5 carbons, the molecular formula is C5H12 (for pentane).
What is the molar mass of 2-pentanone?
Pentane has the molecular structure C5H12 So multiply the number of each atom with its molecular mass. (see the periodic table) 5*12 + 12*1 = 72 gram per mole. Or more accurately: 5*12.01078 + 12*1.007947 = 72.149264 g/mole
Why is the bioling point of hexane greater than that of pentane?
The boiling point of hexane is higher than that of pentane because hexane has a larger molecular mass and stronger London dispersion forces between its molecules. These stronger intermolecular forces require more energy to overcome, resulting in a higher boiling point for hexane compared to pentane.
what mass of pentane gas C5H12 is contained in a 3.0L tank that has a pressure of 1.220 atm at 295K?
pentane
How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
What is the structural isomer of 2-methylbutane?
The structural isomer of 2-methylbutane is pentane. Both 2-methylbutane and pentane have the same molecular formula, C5H12, but differ in the arrangement of carbon and hydrogen atoms.
Why pentane and hexane will dissolve in each other in all proportions?
Pentane and hexane are both nonpolar molecules with similar molecular structures, so they have similar intermolecular forces (London dispersion forces). This allows them to mix together in all proportions because the attractive forces between molecules of the same kind (hexane-hexane, pentane-pentane) and between different kinds (hexane-pentane) are relatively similar in strength.
What do the isomers of pentane always have?
All pentane isomers have always 5 carbon atoms. Besides that, there are 12 hydrogens: C5H12, except cyclopentane (C5H10).
