How many units on a low-dead-space syringe is a 2 mg dose at 6.67 mg/mL?

Asked 26 Sept 2024Modified 22 months agoViewed 14k times

Concretely: a low-dead-space syringe · 2 mg · 6.67 mg/mL.

I want the working, not the result — I need to be able to redo it with different numbers.

I care about the precision as well as the value — I want to know how many figures are real.

Where is my error, and what is the correct working?
