We’re being asked to **determine the density of gallium (Ga).**

Recall that ** density** is the ratio of the mass and volume of an object:

$\overline{){\mathbf{density}}{\mathbf{=}}\frac{\mathbf{mass}}{\mathbf{volume}}}$

Also, the ** volume of a sphere** is given by:

$\overline{){\mathbf{V}}{\mathbf{=}}{{\mathbf{a}}}^{{\mathbf{3}}}}$

where:

**a** = edge length.

**In order to solve this problem we need to:**

**Step 1**. Determine the volume**Step 2**. Determine the mass in grams**Step 3**. Calculate the density

The element gallium (Ga) has the second largest liquid range of any element, melting at 29.78 ^{o}C and boiling at 2204 ^{o}C at atmospheric pressure.

What is the density of gallium in g/cm^{3} at 25 ^{o}C if a 1 in cube has a mass of 0.2133 lb?
