ABOUT DENSITY
--------------------------------
density = mass/volume
density = 7.86 g/cc
FIRST EXAMPLE
--------------------------------
volume = 450 cc
7.86 g/cc = mass / 450cc
mass = 7.86g/cc * 450cc = 3,537g = 3.537kg
SECOND EXAMPLE
--------------------------------
volume = 1.2 cubic metres = 1.2 m^3
volume = (1.2 * (100cm/m)^3) cc = 1,200,000cc
7.86 g/cc = mass / 1,200,000cc
mass = 7.86g/cc * 1,200,000cc = 9,432,000g = 9,432 kg = 9.432 tonne
That's how I would work it out, but feel free to fix it up if there are any errors.

1.78 grams per cubic centimeters is equal to?
1.78 grams per cubic centimeters equals the density of the material that the question talks about.
What is the density of 75 grams and 30 cubic centimeters?
Density: Mass/Volume Answer: 2.5
A ball has a mass of 33.6 grams and a volume of 14.0 cubic centimeters. What is its density?
Density is calculated by mass divided by volume. Thus 33.6 grams / 14.0 cm3 = 2.4 grams/cm3.
What is the volume in cubic centimeters of 1 kilo of silver?
1000 grams of silver with a density of 10,49 has a volume of 95,33 cubic centimeters (a cube 4,47 centimeters on a side).
What is the volume occupied by 6.00g of iron?
You can find the volume of 500 grams of iron by using the formula for density and knowing iron's density. The density of iron is 7.85 grams per cubic centimeters and the formula for density is ggiven by mass divided by volume, or volume is equal to mass divided by density. The volume is 500 grams/ 7.85 grams per cubic centimeters, which is 63.69 cubic centimeters.
What is the density of lead with a mass of 9.92grams?
The density of lead is 11340 kilograms per cubic meters or 11.34 grams per cubic centimeters.
Why can density be measured in grams or per cubic centimeters?
Density cannot be measured in grams, not in "per cubic centimetres".
An object has a mass of 8 grams and a volume of 4 cubic centimeters what is its density?
8 grams/4 cubic centimeters = 2 grams per cubic centimeter
1.78 grams per cubic centimeters is equal to?
1.78 grams per cubic centimeters equals the density of the material that the question talks about.
What is the density if the mass is 408 g?
The density is (408)/(the volume in cubic centimeters) grams per cubic centimeter.
What is the density of 75 grams and 30 cubic centimeters?
Density: Mass/Volume Answer: 2.5
What is the volume of a 17.6 grams sample of lead?
Divide the number of grams by the density (the density of lead is about 11 grams/cubic centimeter - look it up if you need more precision). If the density is in grams/cubic centimeter, the answer is the volume in cubic centimeters.
What is the density of object with 84 grams and 21 cubic centimeters?
Density = Mass/Volume = 84g / 21 cc = 4 grams per cubic centimetre.
What is the density in grams or milliliters of a hydrochloric acid solution which has a mass of 17.84 grams and occupies 15.0 cubic centimeters?
density = mass/volume density = grams/ cubic centimeter 1 cubic centimeter = 1 milliliter density = 17.84/15 = 1.19 grams/milliliter
What is the density of a moon rock that has a volume of 150 cubic centimeters and a mass of 350 grams?
density = mass/volume = 350/150 = 2.33 grams/cubic centimeter
How do you calculate and do density word problems?
density = mass/volume You need to know that mass will be measured in some form of gram, such as grams, milligrams, or kilograms. Volume will typically be measured in milliliters, liters, cubic centimeters, or cubic meters.
A ball has a mass of 33.6 grams and a volume of 14.0 cubic centimeters. What is its density?
Density is calculated by mass divided by volume. Thus 33.6 grams / 14.0 cm3 = 2.4 grams/cm3.
