Thank you so much for this video! This us very helpful! I have a very tough time understanding different topics that many equations and topics mixes in my head. I hope I pass our Pharmaceutical Calculation course subject 🤞
Glad you found the video helpful Roselle. Keep practicing and I am sure you will pass the pharmaceutical calculations course. Thank you for watching and for the comment.
Thank you Jean Christian Ragdi for your question. You may contact us at info@rxcalculations.com. We have a variety of pharmaceutical calculations resources including books, question banks and courses. You may check them out here: www.rxcalculations.com/ .

- each vial has 50 mg / 1 ml. - There are 10 ml in each vial, therefore, we multiply 50mg * 10ml = 500 mg per 10 ml vial. - We need 200 mg, so, do 200/500 = 0.4. This is the value we will use to calculate the amount of the vile we will use, we need 40% of the vile. So we will administer 4 ml of the vial. Hope this helps.
Thank you Wasama for watching and for the comment. In plan A step 4, we are using the osmolarity equation mOsm/L = ((g/L)/MW)x number of particles x 1000. The 1000 is a constant. Since the compound is KCl the number of particles is 2 as KCl dissociates into one potassium ion and one chloride ion. Hope this helps.
Good question Wasama. Whenever we use the osmolarity equation mOsm/L = ((g/L)/MW)x number of particles x 1000, the concentration in the numerator is always grams per liter. So regardless of the volume of solution you always need to calculate the amount in grams that will be present in a 1 liter solution. Thank you for watching. and for the comment.
