Answer:
Number of atoms = 5.1345 x 10²³
Explanation:
Given:
Mass of sodium = 19.6
Find:
Number of atoms
Computation:
We know that atomic mass of sodium is 22.98
So,
Number of atoms = [Mass of sodium/atomic mass of sodium]Avogadro's number
Number of atoms = [19.6 / 22.98]6.02 x 10²³
Number of atoms = 5.1345 x 10²³

When 3,5 dimethyl-4- octene is react with ozone two products are obtain.
2-Methyl butanal and 2 pentanon.
The complete reaction is given in attached file.
Nonpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients. Carbon dioxide and oxygen are two molecules that undergo this simple diffusion through the membrane. The simple diffusion of water is known as osmosis.
