lorasvet [3.4K]

Answer:

See image attached

Explanation:

Ibuprofen is a chiral compound. 'Chiral' means that it has the ability to rotate plane polarised light owing to the presence of an asymmetrically substituted carbon atom. There are two known stereoisomers of the compound; the S- stereoisomer and the R-stereoisomer. The both are shown using wedge and dash perspectives in the image attached.

Only the S- stereoisomer is active as a drug. The R-stereoisomer is gradually converted into the S-stereoisomer in the body. The drug may also be given as a racemic mixture.

ahrayia [7]

Answer:

<h3>The answer is 1.04 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of coke = 21.36 g

volume = 20.5 mL

So we have

density =  \frac{21.36}{20.50}  \\  = 1.0419512...

We have the final answer as

<h3>1.04 g/mL</h3>
