The area where she is flying in windless conditions along the equator is called doldrums. Doldrums is a windless zone at the equator caused by warm rising air. The zone experience bands of showers and storms due to the hot air that rises and cools.
Nothing in particular determines the name of an element, it could range from who discovered it to where it was discovered!

Explanation:
Answer:
Mass = 3.24 g
Explanation:
Given data:
Number of atoms of cobalt = 3.31 × 10²² atoms
Mass of cobalt = ?
Solution:
We will calculate the number of moles of cobalt first.
1 mole contain 6.022× 10²³ atoms
3.31 × 10²² atoms × 1 mol / 6.022× 10²³ atoms
0.0549 mol
Mass of cobalt:
Mass = number of moles × molar mass
Mass = 0.0549 mol × 58.93 g/mol
Mass = 3.24 g
