Answer:
55.3 × 10²³ molecules
Explanation:
Given data:
Number of moles of C₁₁H₁₂O₂₂ = 9.18 mol
Number of molecules = ?
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
For given data:
9.18 mol × 6.022 × 10²³ molecules /1 mol
55.3 × 10²³ molecules
NOTHING really but as the stove is on with water boiling the air get moist
Color

Answer:
The phenomenon of plasmolysis.
Explanation:
When cells of Elodea are placed in a salt solution the phenomenon of plasmolysis occurs and the water will start to move out from the cell. The concentration of salts in the cell will get high due to the diffusion of salt molecules inward. The organelles will look like as they are centered to the cell by hook.
