To find the density of a rock, you need to know its mass and volume. In this case, you have been given the mass of the jagged rock, which is 56 grams. However, the volume of the rock has not been provided. Without the volume, we cannot calculate the density.

To determine the density of the jagged rock, you need to measure or calculate its volume. One way to measure the volume of an irregularly shaped object, like a jagged rock, is to use water displacement. Here's how you can do it:

1. Fill a container with water, such as a graduated cylinder or a beaker, up to a marked level.
2. Carefully drop the rock into the water. Make sure the water level rises but does not overflow.
3. Measure the amount of water that spilled out or the increase in water level. This is the volume of the rock.
4. Record the volume of the rock in milliliters (mL) or cubic centimeters (cm³).

Once you have the volume of the rock, you can calculate its density using the formula: Density = Mass / Volume.

For example, if the volume of the jagged rock is measured to be 40 mL, you can calculate its density as follows:

Density = 56 g / 40 mL

Calculating the division gives you a density of 1.4 g/mL.

Note: It is important to ensure that the units of mass and volume are consistent when calculating density.
