Question

a. Identify the functional groups in enrofloxacin.

b. The recommended dose for enrofloxacin for sheep is $30.mg/kg$of body mass for $5days$. 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 $5days$?

Short 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$64kg$sheep for$5days$

Step-by-step solution

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 $64kg$sheep for $5days$

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

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

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

Mass is equal to the multiplication of volume and density

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

Therefore,

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