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:
- Bronchitis and other ailments.
Aminophylline works by helping to open up your airways, allowing more air into your lungs.

Answer:
The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water.
Answer:
The molar amount of the gas.
Explanation:
If the pressure, volume, and temperature of a gas are known than molar amount can be determine.
Formula:
PV = nRT
P = pressure
V = volume
R = general gas constant
T = temperature
n = number of moles
Example:
V = 2 L, P = 1 atm , T = 273 K , R = 0.0821 atm. L/mol.K
n = PV/RT
n = 1 atm. 2 L / 0.0821 atm. L/mol.K . 273 K
n = 2 / 22.413 /mol
n = 0.09 mol
Answer:
498 kj/mol
Explanation:
Chemical reactions occur as a result of bond breaking and bond formation.
The bonds in reactants are broken and atoms are rearranged to form new bonds.
During bond breaking energy is absorbed to break the bonds of reactants while bond formation involves the release of energy during the formation of new bonds.
In our case;
In 1 mole of the Oxygen molecule, there is one O=O bond
Energy absorbed to break O=O is 498 kJ/mol
Therefore, the ΔH required to break all the bonds in one mole of Oxygen(O₂) molecules is 498kJ/mol.
Note that, bond breaking is endothermic since energy is absorbed from the surroundings.
