Question

Myoglovin, a protein that stores oxygen, has a mass of 2.98 x 10-4____
Would it be milligram, gram or kilogram?

Answer 1

I don't know the context in which this is used (and I assume you made a typo and are talking about myoglobin) but I don't think any one of those units you suggested is correct. From what I could find in Wikepedia, the molar mass is about 16,700; therefore, one molecule would have a mass of about 2.78 x 10^-20 g.
