Thanks for the video, I really learnt a lot but I still unable to solve a similar problem and i'd be glad if could help me with it. A pharmacist is requested to prepare 200g of 15%w/w sulphur ointment. How many grams of 20%w/w sulphur ointment will the pharmacist add to 20g of 12%w/w sulphur ointment to prepare the 15%w/w sulphur ointment. Thanks in anticipation.

[@PharmaceuticalCalculationsEasy]

Thank you Fiyinfoluwa for watching and for the comment. There is a slight contradiction in the question you submitted. Either the total quantity of 15%w/w is not 200g or the amount of the 12% is not 20g. However, the question was solved using the assumption that the 20 g of 12% sulphur ointment is correct. See the solution here: jo.my/alligationsulphur .

How do you know when to use Alligation or C1V1=C2V2? From Namibia

[@PharmaceuticalCalculationsEasy]

Thank you @petrusleevi7267 for watching and for the comment. Generally, you can solve most dilution calculations questions with either the alligation method or the algebraic method (C1V1 = C2V2). However, the alligation method is much faster and has fewer algebra manipulations. Hence, I recommend the alligation method for most dilution calculation questions where the final concentration of your preparation is between the concentration of the components you are mixing together. There is one instance where that alligation method is not suitable and that is for dilution questions where you are required to calculate the final concentration of the preparation. In this situation, use the algebraic method (C1V1 = C2V2). It will save you a lot of time. Hope this helps. Also, please spread the word about the channel if you are finding it useful. It will be much appreciated.

[@anonymousmanifestor5237]

Hi, for the last question, can i do it like 9.1 parts of stock is equal to 100ml? so 0.45 parts is equal to 4.95? The answer is the same, but idk if i got lucky!

[@PharmaceuticalCalculationsEasy]

Yes, you can do that and it should give you the correct answer every time. However, it is better to set it up this way: (9.1/100 mL) = (0.45/X mL) and solve for the unknown X. This is because the 9.1 parts represents the 100 mL and the 0.45 parts represents the volume of the NaCl 10% stock solution. Thank you Bimba for watching and for the comment.

hey man, just wandering if you could solve this Bactroban onitment contains 2% mupirocin. how many grams of a polyethylene glycol ointment base must be mixed with the contents of a 22-g tube of the bactroban ointment to prepare one having a concentration of 5mg/g? anyone please, i couldn't answer this question since i'm doing an advance study and no one could teach me how to answer this

[@PharmaceuticalCalculationsEasy]

+Silent Walker It may be easier to first find the percentage strength of your final concentration as follows: (5 mg/1g) = (y/100g); however, 5 mg is 0.005g hence (0.005g/1g) = (y/100g) solve for y y=(0.005g * 100g)/1g y=0.5% Now, C1Q1 + C2Q2 = C3Q3; (but Q3=Q1+Q2) 2%(22g) + 0%(z) = 0.5% (22 + z); where z is the quantity of PEG. Also, since PEG has no bactroban the concentration is 0%. Solve for z 44 = 11+0.5z 33=0.5z z=33/0.5 z=66 g I hope this helps. Let me know if you have additional questions.

Hi, what would be the easiest way of solving this problem. Thanks in advance. question: An ointment contains 1%w/w calamine. How much calamine powder would be appropriate to add to a 200g of the ointment to produce a 4% w/w calamine ointment?

[@PharmaceuticalCalculationsEasy]

jjazzlyne You may use the algebraic or alligation method. Below is the algebraic method C1Q1+C2Q2=C3Q3 (see kzbin.info/www/bejne/Z6KYoa1virt0qqs) 100x +1(200 g) = 4 (200 g + x) where x is the amount of calamine powder (100%)Solve for x 100x +200 g = 800 g + 4 x x = 600 g/96 x = 6.25 g I hope this helps.
