How do you convert blood plasma range of 11 to 25 mcmol/L of copper (MW=63.55) to mcg/mL?

Question

Tips for knowing what a question like this is asking for.

Answer 1

A question like this is simply asking us to convert from umoles/L to mg/ml. In this case, it is for copper.

We can just use dimensional analysis as follows:

11 umol/L x 63.55 ug/umol = 699 ug/L x 1 L/1000 ml = 0.70 ug/ml

25 umol/L x 63.55 ug/umol = 1589 ug/L x 1L/1000 ml = 1.60 ug/ml

So, the range would be 0.70 to 1.60 ug/ml
