Answer:
Explanation:
We are asked to find the density of a brick. Density is a substance's mass per unit volume. The formula for calculating density is as follows.
The mass of the brick is 100 grams and the volume is 25 cubic centimeters.
Substitute the values into the formula.
Divide.
The density of the brick is <u>4 grams per cubic centimeter.</u>
There's a lot of things built from petroleum, such as toothpaste.
Here's also another list.Gasoline 46%
Heating Oil / Diesel Fuel 20%
Jet Fuel ( kerosene) 8%
Propane / Propylene 7%
NGL / LRG 6%
Still Gas 4%
Petrochemical Feedstocks 2%
Petroleum Coke 2%
Residual / Heavy Fuel Oil 2%
Asphalt / Road Oil 2%
Lubricants 1%
Miscellaneous Products / Special Naphthas 0.4%
Other Liquids 1%
Aviation Gasoline 0.1%
Waxes 0.04%
Kerosene 0.02%
Density = mass/volume
Since there was no condition of unit attached to the question...
Density = 100g/25.0ml
Density = 4g/mL.......
