Question: The following answer was submitted by a freshman student in Chemistry. He was supposed to calculate the density of his object from the lab. a) Discuss the errors he made in terms of form and significant figures.Density is the amount of matter in an object compared to its volume (the amount of space it takes up). If an object were extremely dense, it would feel heavier than another object of the same size that was less dense. For example, a 1-litre soda bottle filled with air would feel much lighter than the same bottle filled with water. Water has a density of 1 kilogram per liter, while air has a ...In a chemistry lab, sources of error can include human error, observation error and problems with equipment.

For solids objects, if it's a simple shape ...Use the metric ruler provided in your lab kit to make linear measurements (measurement of length). Density. Density is an important property of matter because the density does not depend on the amount of a substance. For example, 1 drop of water has the same density as 1 liter of water. Density is determined by dividing the mas Since density is a physical property, it can be used to determine the identity of a substance, as you will do today. To calculate density (d), divide the mass (m) of the object by its volume (V). The most common units for density in chemistry are g/cm3 for solids, g/mL for liquids, and g/L for gases. m.
