Write long answer on what is Isomer? Explain isomer of hexane.

Explanation:

Hexane has five isomers: Hexane, CH3CH2CH2CH2CH2CH3, a straight chain of six carbon atoms. 2-Methylpentane (Isohexane), CH3CH(CH3)CH2CH2CH3, a five-carbon chain with one methyl branch on the second. ... 2,2-Dimethylbutane (neohexane), CH3C(CH3)2CH2CH3, a four-carbon chain with two methyl branches on the second

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
