For each of the compounds described by the following names, 1. draw a three-dimensional representation. 2. star (*) each chiral center. 3. draw any planes of symmetry. 4. draw any enantiomer. 5. draw any diastereomers. 6. label each structure you have drawn as chiral or achiral. (a) (S)-2-chlorobutane (b) (R)-1,1,2-trimethylcyclohexane (c) (2R,3S)-2,3-dibromohexane (d) (1R,2R)-1,2-dibromocyclohexane (e) meso-hexane-3,4-diol, CH3CH2CH(OH)CH(OH)CH2CH3 (f) ({)-hexane-3,4-diol

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.

your answer would be “dry”

it's all four options.
