How is the mass of 1 mole of an element determined

1 answer:

3 0

One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole). The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table.

How does the kinetic energy of solids liquids and gases compare?

maksim [4K]

<h2> <em>QUESTION</em><em>:</em><em> </em><em>how does the kinetic energy of solids liquids and gases compare?</em></h2>

<h2> ANSWER:</h2><h3><em>Gases have the high kinetic energy because its particles are far apart from each other and have negligible fprce of attraction whereas liquids have high force of attraction as compared to gases so they have less kinetic energy then gases,and Solids have high force of attraction between its particles because of that its molecules are closely packed ,so solids do not have kinetic </em><em>energy.</em></h3><h2><em>HOPE</em><em> </em><em>IT </em><em>HELPS </em><em>YOU</em></h2>

Draw the Lewis structure for the compound with the formula COCl2COCl2. Use lines to show bonding electrons.

stira [4]

Answer : The Lewis-dot structure of $COCl_2$ is shown below.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, $COCl_2$

As we know that carbon has '4' valence electrons, chlorine has '7' valence electron and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in $COCl_2$ = 1(4) + 2(7) + 1(6) = 24

According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.
