How many milliliters of an injection containing 250 mg of aminophylline in each 10 ml should be used in filling a medication ord

0.6 milliliters

Let the injection contain X mL of solution.

Then,

An injection containing 250 mg of aminophylline per 10 mL  =  15 mg of aminophylline / X mL of an injection

250 mg / 10 mL = 15 mg / X mL

250 X = 150

X = 15/25

X = 0.6 mL

So, when filling a prescription that calls for 15 mg of aminophylline,

0.6 milliliters of an injection with 250 mg of aminophylline in every 10 ml should be used.

➤ A sterile, nonpyrogenic solution of aminophylline in water is known as aminophylline injection, USP. Anhydrous theophylline weighs about 79% as much as aminophylline (dihydrate). Aminophylline Injection is injected slowly into the vein, or it can be diluted and infused slowly into the vein.

What is the purpose of aminophylline injection?

Aminophylline is used to treat breathing issues that could be brought on by:

  • Asthma
  • Emphysema
  • Bronchitis and other ailments.

Aminophylline works by helping to open up your airways, allowing more air into your lungs.

What is the molar concentration of a 2 liter solution containing 200 grams of glucose?
NARA [144]

The molar concentration is 1.11M.

<h3>What is molar concentration?</h3>

The phrase "molar concentration" (also known as "molarity," "amount concentration," or "substance concentration") refers to the amount of a substance per unit volume of solution and is used to describe the concentration of a chemical species, specifically a solute, in a solution. The most frequent measure of molarity in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units. A solution with a concentration of 1 mol/L is referred to as 1 molar, or 1 M.

<h3>Given : </h3>

Volume of the solution = 2L

Mass of glucose given = 200g

Concentration of glucose= ?

<h3>Formula use: </h3>

Molarity = no. of moles of solute / volume of the solution (L)

Moles of solute = given mass of solute / molar mass of the solute

<h3>Solution: </h3>

No. of moles of solute( glucose ) = 200 / 180 = 1.11 moles'

Molarity = 1.11 / 2 = 0.5555 mol L ^(-1)

Therefore, the molar concentration of glucose in the solution = 0.555 mol L ^(-1)
