Q. 14.48 - An Introduction to General, Organic, and Biological Chemistry

Question

a. Identify the functional groups in enrofloxacin.

b. The recommended dose for enrofloxacin for sheep is $30. mg/kg$ of body mass for $5 days$. Enrofloxacin is supplied in $50.-mL$ vials with a concentration of $100. mg/mL$. How many vials are needed to treat a $64-kg$ sheep for $5 days$?

Step-by-Step Solution

Answer

(a) The functional groups in enrofloxacin are amino groups, a carboxyl group, a keto group, and an aromatic benzene ring

(b) There are two vials needed to treat a $64 kg$ sheep for $5 days$

Part (a) Step 1: Given information

We need to find out the functional groups in enrofloxacin 

Part (a) Step 2: Explanation

From the structure of Enrofloxacin, we get

Enrofloxacin has -

Three amino groups 

A carboxyl group 

A keto group

An aromatic benzene ring.

Part (b) Step 1: Given information

The recommended dose for enrofloxacin for sheep is $30mg/kg$ of body mass for five days. Enrofloxacin is supplied in $50ml$ vials with a concentration of  $100mg/ml$

We need to find out the no. of vials needed to treat a $64 kg$ sheep for $5 days$

Part (b) Step 2: Explanation

We know that 

Enrofloxacin recommended for a sheep is equal to the multiplication of the mass of sheep and body mass

$64kg\times 30 mg/kg=1920 mg$

For 5 days, $1920\times 5=9600 mg$

Mass is equal to the multiplication of volume and density 

$50 ml\times 100 mg/ml=5000 mg$

Therefore, 

No. of vials, $\frac{9600}{5000}=1.92\approx 2$
