penelope was in charge of collecting firewood. The firewood she found had a mass of 120 g and a volume of 480 cm3 what is the density of the firewood explain the steps you took to solve this problem.
Answers
Answer:
Density = 0.25 g/cm³
Explanation:
Firstly, the density of a body is the mass of that body divided by it volume. The density gives the idea of the relationship between the mass of a body and the space which it occupies(volume). How tightly packed the atoms that makes up the body, affects the density of every substance. If the substance has a large mass and the atoms are well arrange to fill all the spaces the density is expected to be high.
In the case of fire wood that has life initially, due to the sparsely packed nature of the cells the firewood is bound to have a low density because the mass are not occupying as much space as possible.
The mass of the firewood is already measured and known likewise the volume. Base on the formula for calculating density which is ;
Density = mass/volume
Density = 120/480
dividing through
Density = 1/4
converting the fraction to decimal
Density = 0.25 g/cm³
The density of the firewood is 0.25 gram per centimeter cube
Answer:
mass = 120 g
volume = 480 cm3
density = mass/ volume
=120/480
=0.25g/cm2
