<h3>Molar mass of Ammonia:-</h3>

\\ \sf\longmapsto NH_3

\\ \sf\longmapsto 14u+3(1u)

\\ \sf\longmapsto 14u+3u

\\ \sf\longmapsto 17u

\\ \sf\longmapsto 17g/mol

Moles of Ammonia:-

\boxed{\sf No\:of\:moles =\dfrac{Given\:mass}{Molar\:mass}}

\\ \sf\longmapsto No\:of\:moles=\dfrac{17}{17}

\\ \sf\longmapsto No\;of\:moles=1mol

  • Volume of solution=0.50L

We know

\boxed{\sf Molarity=\dfrac{Moles\:of\:solute}{Volume\:of\: Solution\:in\:L}}

\\ \sf\longmapsto Molarity=\dfrac{1}{0.50}

\\ \sf\longmapsto Molarity=2M

Explanation:

Because molarity is mol/L, we'll have to convert 17g to mol.

After obtaining the mol, we'll divide that by the volume to obtain Molarity.

How does the energy of the atoms in a hot cup of coffee compare to the energy of the atoms in a piece of ice?
Nonamiya [84]

Answer:

The atoms in the cup of coffee have more energy.

Explanation:

The difference between the hot cup of coffee and the piece of ice is their temperature. The hot cup of coffee has a higher temperature than the ice.

The relationship between the energy and temperature is a direct relationship. This means that higher temperature means higher kinetic energy and vice versa.

Since the hot cup of coffee has  a higher temperature, it means it also have the highest amount of energy. The correct option is;

The atoms in the cup of coffee have more energy.
