If I reconstitute a 15 mg vial with 1.5 mL of phosphate-buffered diluent, what concentration do I end up with?

Asked 8 Jun 2025Modified 14 months agoViewed 9.1k times

The specifics, since they change the answer: 15 mg · 1.5 mL · phosphate-buffered diluent.

I would like the arithmetic checked rather than the conclusion asserted.

I have deliberately not used an online calculator because I want to be able to check the result.

Can someone show the working rather than just the answer?
