If a sample contains 70.0 % of the R enantiomer and 30.0 % of the S enantiomer, what is the enantiomeric excess of the mixture?
NeTakaya

Answer:

the enantiomeric excess of the mixture is 40%

Explanation:

The computation of the enantiomeric excess of the mixture is shown below:

As we know that

= |\frac{R - S}{R + S} |\times 100\\\\= |\frac{70 - 30}{70 + 30}| \times 100\\\\= 40\%

Hence, the enantiomeric excess of the mixture is 40%

Rx: Codeine phosphate 30 mg/tsp Tussin syrup 30mL Elixophyllin qs 240 mL Sig: 5mL qid pc hs If 5 mL of Tussin syrup contains 100
kotykmax [81]

Answer:

50 mg.

Explanation:

From the prescription, 240 ml amount is to be prepared containing 30 ml tussin syrup. As the frequency is 5 mL qid, it means 5mL of syrup is to be administered four times daily i.e. 20 mL daily. To calculate the amount of tussin taken daily,

<em>                          </em><em><u>30 mL tussin</u></em><em> = </em><em><u>X mL of tussin</u></em>

<em>                     240 mL solution    20ml solution</em>

⇒ 2.5 mL of tussin

5 ml tussin contains 100mg guafenesin,

So,

⇒ 2.5 ml of tussin contains 100x2.5/5 = 50 mg guaifenesin
