Hi Julie,
I am glad that I was able to help you. Remember, the units are the most important part of the problem. They will always tell you how to solve the problem. The numbers just go along for the ride. Let me know if you have any specific questions. Also, you can download my handout book and exercises from the main channel page.

Hi Evans,
First of all, it is always best to put a leading zero on your decimals. 0.25 rather than .25. If you multiplied 0.25 x 100 g you would have 25 g, right? Treat the % sign just like any other unit. Remember, 100% is the same as 1.
Think about this a little and I think you will see that 0.25 x 100% is 25%.

Hi Brian,
Thanks for the nice comment. These problems really are not that hard once you understand what you are actually doing.

Hi Chirs,
Since you are just mixing two solutions together you would just calculate 50% of the 500 mL for the Betadine and 50% of the 500 mL for the normal saline. It doesn't matter what the composition of the Betadine or NS is. The answer would be 250 mL of each.

If you want to change 50mg/5ml into a percent strength, the units of the answer will be %g/ml. You have to add the % by multiplying by 100% and you have to change 50mg into g by multiplying by 1g/1000mg. You don't have to do anything with the 5ml. 50mg/5ml (100%)(1g/1000mg) = 1%g/ml or 1% w/v
