How many moles are there in 3.612 x 1024 molecules of CaO?
melamori03 [73]

The number of moles in  3.612 x 10²⁴ molecules of CaO is  6 moles.

<h3>Number of moles in the molecules</h3>

The number of moles in  3.612 x 10²⁴ molecules of CaO is calculated as follows;

6.02 x 10²³ molecules = 1 mole

3.612 x 10²⁴ molecules = ?

= (3.612 x 10²⁴ ) / (6.02 x 10²³ )

= 6 moles

Thus, the number of moles in  3.612 x 10²⁴ molecules of CaO is  6 moles.

The bond between which two atoms has the greatest degree of polarity
Alenkasestr [34]

Answer:

By comparing  the bonds between C-H and O-H, the O-H bond has the greatest degree of polarity.

Explanation:

Based on bond electronegative values which is a measure of the ability of a atom in a chemical bond to pull the shared electrons closer to its self.

The electronegativity of an element characterizes the elements chemical reaction.

From the available bonds

Oxygen has an electronegativity value of 3.44 and Carbon 2.55, while  Hydrogen has an electronegativity value of  2.20

Therefore the bond between carbon and hydrogen is much less polar than between oxygen and hydrogen.

The bond between oxygen and hydrogen has the greatest polarity.
