To calculate the mass of an object you must first know its density and its volume. Finding its density can help you determine that. So we need to draw a bar which goes from 20 to 35 on the textx-axis and up to 06 on the.
This chemistry video tutorial explains how to solve density problems.
Thus Population Density Number of PeopleLand Area. Density Mass Volume. Density Mass Volume. To find the volume use the formula for the volume of a box.
