Answer:
26,167.47m
Explanation:
Problem:
We are to solve this problem using dimensional analysis:
from the given conversion factors-
0.621mi = 1.00km
1km = 1000m
From the problem, we are groing from miles to metres:
16.25mi x
x 
The mi will cancel out and also the km. This leaves us with the desired unit we want which is meters, m.
= 26,167.47m
For Iron:

For Oxygen:

These are the two chemical symbols for the two elements found in Iron Oxide.
Yes, it mixes it and has vitamins in the tea.
