Questions and answers on how to convert things from one unit or system to another
Forum rules
Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

How was this done, please help me maam/sir

1.. Sodium heparin (10000 IU/ml) was added to physiological saline (0.9%) to make 1 liter solution with final concentration of 500 IU/ml.

2. Sodium heparin (10000 IU/ml) and Polyvinylprrolidone was added to physiological saline (0.9%) to make 1 liter solution with final concentration of 500 IU heparin/ml and 1 g PVP/ml in final solution.

How was this done
Thanks
NOR

Is the second part of your problem in error? Dissolving another 1 g/mL of anything in water or saline seems an awfully strong soltuion, since water weighs 1 g/mL.
