Question

the recommended daily allowance (rda) of the trace metal magnesium is 410 mg/day for males. express this quantity in µg/day. express your answer in micrograms per day.

Explanation:

Step1: Recall the conversion factor

We know that \(1\space mg = 1000\space \mu g\) (since "milli" means \(10^{-3}\) and "micro" means \(10^{-6}\), so \(1\space mg=10^{3}\space \mu g\)).

Step2: Convert 410 mg to μg

To convert milligrams to micrograms, we multiply the number of milligrams by 1000. So for 410 mg, we do the calculation: \(410\space mg\times1000\space \frac{\mu g}{mg}\)

\[
410\times1000 = 410000
\]

Answer:

410000
