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

The recommended daily allowance (RDA) of the trace metal magnesium is 4.1 x 10^5 μg/day or 410 mg/day.  

Further Explanation:

This is an example of a unit conversion problem. To solve this, recall the following conversion factors:

1 g = 1000 mg

1 g = 1,000,000 μg

To convert the given RDA, the following steps may be carried out:

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m

sadly i believe the answer is d
