While digging in the backyard, you find an old coin. it’s mass is 26.76 g and it’s volume is 3 cm . what is the density?

Considering the definition of density, the density of the old coin is 8.92 .

It is neccesary to know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance, that is, density is the relationship between the mass of a substance and the volume it occupies.

Mathematically, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

In this case, you know:

Replacing in the definition of density:

Solving:

density= 8.92

The density of the old coin is 8.92 .

Learn more about density:

Density = mass/volume

26.76/3 = 8.92

The density is 8.92

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
