Answer:
<u>Flow rate = 16.67 gtts/min rounded to 17 gtts/min</u>
Explanation:
In order to calculate the flow rate, the following formula will be used.
Flow rate (gtts/min) =
50 mL of fluid in which Ciprofloxacin is dissolved is taken as volume.
<u>KNOWN DATA:</u>
Volume = 50mL
Time = 45 minutes
Drop factor = 15 gtts/mL
Flow rate = unknown
<u>CALCULATION:</u>
Plugging the known values in the formula,
Flow rate (gtts/min) =
Flow rate = x 15
<u>Flow rate = 16.67 gtts/min.</u>

Answer:
We need 5 tablets.
Explanation:
We need to prepare 250 mL of a 1 : 5 solution.
When we are talking about solutions , '' a : b '' is known as the solution ratio.
Where ''a'' and ''b'' are integer numbers.
In our exercise, we have a 1 : 5 solution ratio. This means that we will have 1 gram of solute for each 5 mL of solution.
To calculate the mass of solute we can write the following :
Notice that we equalize the solution ratio to the mass of solute '''' divided by the total volume of solution (250 mL).
Solving for ⇒
⇒
We found out that we need 50 g of solute.
Given that each tablet has 10 g of solute ⇒
We need five 10-gram tablets to prepare the solution.
