Answer:
1 x 10^13 stadiums
Explanation:
We are given that;
1 stadium holds = 1 × 10^5 people
Number of iron atoms is 1 × 10^18 atoms
Assuming the stadium would carry an equivalent number of atoms as people.
Then, 1 stadium will carry 1 × 10^5 atoms
Therefore,
To calculate the number of stadiums that can hold 1 × 10^18 atoms we divide the total number of atoms by the number of atoms per stadium. Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18
atoms ÷ 1 × 10^5 atoms/stadium =
1 × 10^13 Stadiums
Thus, 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
