Measuring the Density of an Irregular Shaped Object

Calculating the density of irregular objects II Density of Irregular Shape Solid II STEM Activity

A supposedly gold nugget displaces 19.3 mL of water and has a 
mass of 371 g. Could the nugget be made of gold?

A piece of unknown solid weighs approximately 0.045 lbs. When a scientist places it in a glass beaker the water level increases from 200 mL to 260 mL. What is the density of the unknown solid in g/mL?<img src="https://static.studychannel.pearsonprd.tech/courses/general-chemistry/thumbnails/images/4cfd2978"alt=""/>

A 25.5 g sample of a metal was placed into water in a gradu-ated cylinder. The metal sank to the bottom, and the water level rose from 15.7 mL to 25.3 mL. What is the identity of the metal? (LO 1.9) 
(a) Tin (density = 7.31 g/cm3) (b) Lead (density = 11.34 g/cm3) (c) Silver (density = 10.49 g/cm3) (d) Aluminum (density = 2.64 g/cm3)

You would like to determine if a set of antique silverware is pure silver. The mass of a small fork was measured on a balance and found to be 80.56 g. The volume was found by dropping the fork into a graduated cylinder initially contain-ing 10.0 mL of water. The volume after the fork was added was 15.90 mL. Calculate the density of the fork. If the den-sity of pure silver at the same temperature is 10.5 g/cm3, is the fork pure silver?

MEASURING THE DENSITY OF AN IRREGULAR SOLID - science experiments to try yourself

video, how to find density of an irregular solid

A 32.65-g sample of a solid is placed in a flask. Toluene, in
which the solid is insoluble, is added to the flask so that the
total volume of solid and liquid together is 50.00 mL. The
solid and toluene together weigh 58.58 g. The density of toluene
at the temperature of the experiment is 0.864 g>mL.
What is the density of the solid?

A titanium bicycle frame displaces 0.314 L of water and has a
mass of 1.41 kg. What is the density of the titanium in g>cm3?

SI Units

The International System of Units (SI) is related to the metric system and is based on seven base units.

Physical & Chemical Changes

A physical change involves a change in the phases of matter, whereas a chemical change involves a change in chemical bonds.&nbsp;

Physical Properties

Physical Properties are measurable properties that describe the state of chemical compounds.&nbsp;

Significant Figures: In Calculations

Significant Figures are often involved in chemical calculations.&nbsp;

Scientific Notation

Scientific Notation is used to turn small or large inconvenient numbers into manageable ones.&nbsp;

The density of non-geometric objects can be determined using water displacement.&nbsp;

Density

Density represents the mass of an object or compound within a given volume.&nbsp;

Significant Figures: Precision in Measurements

Significant Figures are used to discuss the level of precision in any measurement.&nbsp;

Intensive vs. Extensive Properties

Intensive Properties are independent and Extensive Properties are dependent on the size or amount of substance present

Density of Geometric Objects

The density of geometric objects generally includes spheres, cubes and cylinders.&nbsp;

Significant Figures

Significant Figures are used to determine some level of accuracy within our recorded measurements.&nbsp;

Dimensional Analysis

We use dimensional analysis&nbsp;as a fail proof process to convert from one unit to another.

Chemical Properties

Chemical Properties are observed during chemical reactions.&nbsp;

Temperature

Temperature is a measure of the amount of average kinetic energy of the atoms in a compound.

Metric Prefixes

Metric Prefixes are “labels” that can be placed in front of base units.&nbsp;

Conversion Factors

Conversion Factors represent ratios or fractions composed of different units.&nbsp;

Classification of Matter

Chemistry is the study of matter and the changes it undergoes, with the atom being its basic functional unit.&nbsp;
