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

er calling for 15 mg of aminophylline?
Chemistry

Serhud [2]1 year ago

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.

The specific rotation of (S)-2-butanol is +13.5. If 0.119 g of its enantiomer is dissolved in 10.0 mL of ethanol and
larisa86 [58]

Answer:

+15.8°

Explanation:

The formula for the observed rotation (α) of an optically active sample is

α = [α]<em>lc </em>

where

<em>l</em> = the cell path length in decimetres

<em>c</em> = the concentration in units of g/100 mL

[α] = the specific rotation in degrees  

1. Convert the concentration to units of g/100 mL

c = \frac{\text{0.119 g}}{\text{10.0 mL}} \times \frac{10 }{10 } =\frac{\text{1.19 g}}{\text{100 mL}}

2. Calculate the observed rotation

\alpha = (+13.3 ^{\circ}) \times 1.19 \times 1 = +15.8^{\circ}

What’s the density if the mass is 40.8g and the volume is 60mL?
luda_lava [24]

Answer:

We have the final answer as

<h2>0.68 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 40.8 g

volume = 60 mL

The density is

density =  \frac{40.8}{60}  \\

We have the final answer as

<h3>0.68 g/mL</h3>

Hope this helps you

how many electrons does silver have to give up in order to achieve a sido noble gas electron configuration
andrezito [222]

Answer:

Silver has to give up one electron.

Explanation:

Silver is a transition element and has a partially filled 4d- orbital having 9 electrons and a 5s orbital having 2 electrons in it. In order to achieve stability, silver must have completely filled d-orbital having a maximum number of 10 electrons in it.

Therefore, one electron from 5s orbital jumps to 4d orbital to make it stable. Now, 5s orbital has only one electron, and it will be easy for silver to lose this electron to attain a stable electronic configuration.
