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:+1/2 and -1/2.
Explanation:the presence of an external magnetic field (B0), two spin states exist, +1/2 and -1/2.
The magnetic moment of the lower energy +1/2 state is aligned with the external field, but that of the higher energy -1/2 spin state is opposed to the external field.
This is a build up of lava which came out of the volcano in previous eruptions, once this lava came out of the volcano it cooled and hardened, over many eruptions layers of hardened volcanic rock will form. The layers are slanted as gravity acts on the lava so it flows down and a little further from the cone.
Physical is texture. chemical is ability to react with other elements. chemical is ability to conduct heat. hardness is physical. lack of ability to rust is chemical. state is physical.
Answer:
1.50 × 10²⁴ atoms C
Explanation:
Step 1: Define
Molar mass of C - 12.01 g/mol
Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units, etc.
Step 2: Use Dimensional Analysis
= 1.50375 × 10²⁴ atoms C
Step 3: Simplify
We are given 3 sig figs.
1.50375 × 10²⁴ atoms C ≈ 1.50 × 10²⁴ atoms C
