This problem is asking for the intermolecular forces in ethanamine, C₂H₅NH₂. Hence, after analyzing it, we find they are both London dispersion forces and hydrogen bonding.

<h3>Intermolecular forces</h3>

In chemistry, intermolecular forces are the responsible of holding molecules together both in liquids and solids, and they depend on the type of bonds exhibited by the molecule. In this case, ethanamine:

$CH_3-CH_2-NH_2$

Has C-C, C-H, C-N and N-H bonds. Now, C-C, C-H and N-H are strongly nonpolar as they have an electronegativity difference below 0.7, which means ethanamine has London dispersion forces as the weakest ones.

In addition, the presence of N-H bonds, provides this molecule with stronger intermolecular forces, hydrogen bonding, which occur in N-H and O-H bonds.

How many moles of methane (CH4) is<br> 6.70 x 1022 atoms of methane?

suter [353]

Answer:

0.1113 mol

Explanation:

Data Given:

no. of atoms of CH₄= 6.70 x 10²² atoms

no. of moles of methane (CH₄) = ?

Solution:

we will find no. of moles of methane (CH₄)

Formula used

no. of moles = no. of atoms / Avogadro's number

Where

Avogadro's number = 6.022 x 10²³

Put values in above equation

no. of moles = 6.70 x 10²² atoms / 6.022 x 10²³ (atoms/mol)

no. of moles = 0.1113 mol

So,

There are 0.1113 moles of methane.
