Answer: The volume in ml that should be drawn is 2.4ml.
Explanation:
Heparin is an anticoagulant which is administered to prevent the formation of blood
clot in high risk patients. The high risk patients include those undergoing open-heart surgery, bypass surgery, kidney dialysis, and blood transfusions. This medication can be administered subcutaneously ( that is, under the skin) by a health care provider. The exact dosage should be administered to avoid adverse effects.
From the question given,
In 5 ml of stock ampoules, there are 25,000 units.
To calculate how many millilitres will deliver 1 unit, divide by 25,000
5 ÷ 25000 = 0.0002
Therefore 0.0002 ml will deliver 1 Unit.
To calculate the volume that will deliver 12,000 units, multiply by 12,000.
Therefore,
12,000 × 0.0002 = 2.4mL
From the calculation, the volume in ml that should be drawn is 2.4ml

They dont have the same fingerprints? I always thought it was the same~
Taking into account the definition of molarity, the molar concentration of the table salt is 1.368 .
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
<h3>Molar concentration of the table salt</h3>
In this case, you have:
- number of moles= 10 g×= 0.171 moles [being the molar mass of NaCl]
- volume= 125 mL= 0.125 L [being 1000 mL= 1 L]
Replacing in the definition of molarity:
Solving:
<u><em>molarity= 1.368 </em></u>
Finally, the molar concentration of the table salt is 1.368 .

Answer:
I don't know for sure, but I would probably say abdomen because there are not very many bones to view in the abdomen so it might be a bit of a useless x ray
