How would you describe the solid-state in terms of motion (ability to move in the space and speed) and distance between molecule
horrorfan [7]

In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

According to the kinetic theory of matter, the molecules that compose matter are in constant random motion. The nature of this motion varies in the three states of matter which are;

  • Solid
  • Liquid and
  • Gas

In the solid state, the molecules do not translate, they only vibrate and rotate about their mean positions. In the liquids state, the molecules translate but they still have restricted degrees of freedom due to intermolecular interactions. In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

Using today's current price of gold - $1838.80 per troy ounce, how much are 5.17x1017 atoms of gold worth? (Hint: You will have
Zepler [3.9K]

Answer:

0.010 $.

Explanation:

Hello!

In this case, since 1 troy ounce equals 31.1 grams, we can compute the price of gold per gram first:

1,838.80\frac{\$}{try\ ounce} * \frac{1try\ ounce}{31.1g}  = 59.1\frac{\$}{g}

Now, we need to compute the grams of copper in 5.17 x10¹⁷ atoms via the Avogadro's number:

m=5.17x10^{17}atomsAu*\frac{197.0gAu}{6.022x10^{23}atomsAu} \\\\m=1.69x10^{-4}g

Thus, the price is:

\$ = 59.1\frac{\$}{g}*1.69x10^{-4}g \\\\\$ =0.010\$

Best regards!
