Calculating Density of Unknown Substances

What is the formula for calculating density?

• D = M + V

• D = M / V

• D = M * V

• D = V / M

Which unit is used to measure the density of solids?

• Grams per cubic centimeter

• Kilograms per liter

• Pounds per cubic inch

• Grams per milliliter

What equipment is needed to measure the mass of a sample?

• Thermometer

• Beaker

• Pan balance or digital scale

• Graduated cylinder

How do you find the volume of an irregular solid?

• Using a ruler

• Using the water displacement method

• Using a digital scale

• Using a thermometer

If a sample has a mass of 10 grams and a volume of 5 cubic centimeters, what is its density?

• 0.5 grams per cubic centimeter

• 2 grams per cubic centimeter

• 5 grams per cubic centimeter

• 10 grams per cubic centimeter

What is the difference between density and mass?

• Density is mass per unit volume, while mass is the amount of matter in an object

• Density is the amount of matter in an object, while mass is mass per unit volume

• Density and mass are the same

• Density is measured in grams, while mass is measured in liters

Why do hot air balloons rise?

• Because hot air is denser than cold air

• Because the balloon is lighter than air

• Because of the wind

• Because hot air is less dense than cold air

Why do ships float even though they have a large mass?

• Because their mass is spread over a large surface area, reducing their density

• Because they are made of light materials

• Because of the salt in the water

• Because they are hollow
