This stadium can hold 100,000, or 1  x  105, people. the number of atoms in a grain of iron is about 1  x  1018. would you need 1  x  1010  or 1  x  1013  stadiums to hold the same number of people as the number of atoms in a grain of iron? explain your answer.

1 x 10^13 stadiums

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

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

the answer is true. hope it .
