The recommended daily allowance (RDA) of the trace metal magnesium is 410 mg/day for males. Express this quantity in μg/day.

Answers

The recommended daily allowance (RDA) of the trace
 metal magnesium for males = 410 mg/day
Now we know that
1 mg = 1000 μg
So
410 mg/day = (410 * 1000) μg/day
                   = 410000 μg/day
So the recommended daily allowance (RDA) of the trace
metal magnesium for males = 410000 μg/day
