Thank you so much for putting this video up.. I open each math video I find on youtube with a negative outlook assuming I am only going to have wasted my time watching because there will be some step assumed & when that gets skipped over I am done for... You are great with doing the pictures & explaining piece by piece--excites me I might be able to understand some more.

I just worked this out on my own and I'm shocked that I figured it out. Thanks for this video and great step by step instructions and explanation!

Good! Thank you for watching!

@ptcbtutor Quick question! The tic-tac-toe method might also work out this problem? I kinda tried it but with no luck yet. Thanks.

@ea313712

The only way, as far as I know, that tic-tac-toe will work is, if what you are looking for are both the initial volumes.

Good observation!

Please help solve:

TPN orders. A physician writes and order for Aminosyn 2.5% 500 ml. You look on the shelf and have only Aminosyn 8.5% 500 ml. How are you going to prepare this order using a sterile evacuated container?

what method would you use to solve this?

This has helped a lot, I am on the MPharm course and I find this incredibly useful with the use of the visual explanations as well as the well explained formulas for solving this type of question. Thanks! :)
