A$.$ Density

The basic formula for density is $D=$ mass volume. It describes how closely packed the particles of a Solids typically have the highest density, followed by liquids then gases. $,$ a substance with a smaller density will rise above a substance with a greater y$.$ This is why helium balloons float in air. To determine the density of a solid, simply find the and volume of the solid and perform the calculation. The mass is easy to find on a balance, but volume can be found by direct measurement with a ruler or by displacement in a graduated cylinder. If the object is an irregular shape, displacement has to be used. The amount of water that is displaced is equal to the volume of the object. For example, if a graduated cylinder contains $12\mathrm{.}0mL$ of water and an object is added to the cylinder, the water level rises to $17\mathrm{.}4mL.$ The volume of the object is calculated as $5\mathrm{.}4mL(17\mathrm{.}4mL-12\mathrm{.}0mL).$ Find the density of the metal object given to you.
