Answer:
Mass = 4.5 g
Explanation:
Given data:
Number of atoms of iron = 4.85 ×10²² atoms
Mass of iron = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
4.85 × 10²² atoms of iron / 6.022 × 10²³ atoms × 1 mol
0.081 mol
Mass of iron:
Mass = number of moles × molar mass
Mass = 0.081 mol × 55.85 g/mol
Mass = 4.5 g
The ionic formula of sodium oxide would be Na20
Answer:
The variation of sunlight reaching Earth is one cause of ice ages. Over thousands of years, the amount of sunshine reaching Earth changes by quite a lot, particularly in the northern latitudes, the area near and around the North Pole.
