What is the formula for density?
Volume divided by mass
Mass multiplied by volume
Mass plus volume
Mass divided by volume
Density is defined as an object's mass per unit volume, which is why the correct formula is mass divided by volume. This relationship helps describe how compact matter is within a substance. For more details on density calculations, see Density - Wikipedia.
Which SI unit is commonly used for density?
Newtons per square meter (N/m²)
Grams per cubic centimeter (g/cm³)
Grams per liter (g/L)
Kilograms per cubic meter (kg/m³)
The SI base unit for density is kilograms per cubic meter (kg/m³), reflecting mass in kilograms over volume in cubic meters. Although grams per cubic centimeter is common in labs, kg/m³ is the standard SI unit. For unit standards, refer to SI Units - Wikipedia.
A sample has a mass of 200 grams and a volume of 50 cubic centimeters. What is its density?
4 g/cm³
0.25 g/cm³
100 g/cm³
250 g/cm³
Density equals mass divided by volume: 200 g ÷ 50 cm³ = 4 g/cm³. This simple calculation shows how much mass is packed into each cubic centimeter. For further practice, see Density Calculations.
An object has a density of 8 g/cm³ and a volume of 10 cm³. What is its mass?
80 g
0.8 g
18 g
0.8 kg
Mass is obtained by multiplying density by volume: 8 g/cm³ × 10 cm³ = 80 g. This reverses the density formula to find mass. See more examples at Khan Academy: Density and Mass.
Which of the following materials will float when placed in water?
Aluminum (density ? 2.7 g/cm³)
Wood (density ? 0.6 g/cm³)
Copper (density ? 8.9 g/cm³)
Iron (density ? 7.8 g/cm³)
An object floats if its density is less than that of water (1 g/cm³). Wood, with a density around 0.6 g/cm³, is less dense and therefore floats. For a discussion of buoyancy and density, see Buoyancy - Wikipedia.
A metal cube displaces 12 cm³ of water and weighs 96 grams. What is the density of the metal?
4 g/cm³
12 g/cm³
72 g/cm³
8 g/cm³
Using water displacement gives volume; density = mass/volume = 96 g ÷ 12 cm³ = 8 g/cm³. This method applies Archimedes' principle to find volume. More on this technique at Archimedes' Principle - Britannica.
Convert a density of 0.85 g/cm³ to kilograms per cubic meter (kg/m³).
850 kg/m³
0.85 kg/m³
8500 kg/m³
85 kg/m³
1 g/cm³ equals 1000 kg/m³, so 0.85 g/cm³ × 1000 = 850 kg/m³. Unit conversion is key in density problems. See unit conversion tables at RapidTables: cm³ to m³.
A wooden block has a density of 600 kg/m³ and floats in water (density 1000 kg/m³). What fraction of its volume is submerged?
100%
60%
10%
40%
For a floating object, the submerged fraction equals the object's density divided by fluid density: 600/1000 = 0.6 or 60%. This principle arises from equilibrium of buoyant force and weight. More on flotation at Flotation - Wikipedia.

Study Outcomes

  1. Understand Density Fundamentals -

    Define density as mass per unit volume and explain how this ratio characterizes the composition of different materials.

  2. Calculate Density from Mass and Volume -

    Use the density formula (density = mass/volume) to compute densities for various solids and liquids given their mass and volume measurements.

  3. Apply Density Calculations in Practical Scenarios -

    Perform density computations to solve contextual problems, such as identifying materials or predicting how objects behave in different fluids.

  4. Analyze Density Variations -

    Examine how changes in mass or volume affect an object's density and interpret the implications of these changes.

  5. Interpret Real-World Density Examples -

    Recognize density patterns in everyday materials and use comparative reasoning to estimate densities of unknown objects.

  6. Evaluate Density Trivia Challenges -

    Solve targeted questions about density with accuracy, reinforcing understanding through an engaging and interactive quiz format.

Cheat Sheet

  1. Definition and Formula of Density -

    Density is defined as the mass per unit volume of a substance, expressed by the formula ϝ = m/V. This simple ratio underpins every question for density and helps you crack a density calculation quiz with ease. For instance, if an object has a mass of 10 g and occupies 2 cm³, its density is 5 g/cm³.

  2. Standard Units and Conversions -

    The SI unit for density is kilograms per cubic meter (kg/m³), while many labs use grams per cubic centimeter (g/cm³) for smaller samples. To convert, remember that 1 g/cm³ equals 1000 kg/m³, a handy trick for density trivia quiz questions. Accurate unit conversions ensure you never lose points on density calculation quizzes.

  3. Volume Measurement Techniques -

    Accurate density questions about density often involve measuring volume via fluid displacement or geometric formulas. For irregular objects, Archimedes' principle and a graduated cylinder reveal volume by the rise in water level. Consistent technique reduces error, boosting confidence when you face tricky density trivia quiz items.

  4. Buoyancy and Density Relationships -

    Buoyancy arises from differences in density between an object and the fluid it's immersed in, governed by Archimedes' principle. If an object's density is lower than the fluid's, it floats; if higher, it sinks - core concepts in many density trivia quizzes. Visualize ice cubes on water to master this floating-versus-sinking logic.

  5. Memorization Mnemonic: MTV -

    Remember "MTV" to recall Density = Mass ÷ Volume each time you tackle mass volume density questions. This catchy mnemonic makes density calculation quiz questions feel like a breeze and sticks better than rote repetition. Practice with a few sample problems - like finding the density of a metal block - to cement your knowledge.
