Answer:

Explanation:
According to the ideal gas law equation:

Let's express the number of moles in terms of mass and molar mass:

Let's divide both sides by volume:

Notice that:

So the equation becomes:

Expressing density:

Substituting the given values:

Answer:
Its melting point is 17 °C.
Explanation:
- The melting point of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium.
<em>So, the melting point is 17 °C.</em>
And this is shown in the figure attached.
