Explanation:
I already learned this last year.
On average mercury is closest to earth
Answer:
11.442E23molecules
Explanation:
Given data:
Number of moles of water = 1.9 mol
Number of molecules of water = ?
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,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
In 1.9 moles:
1.9 mol × 6.022 × 10²³ molecules / 1 mol
11.442 × 10²³ molecules
In e notation:
11.442E23 molecules
