Thank you for posting your question here. I am just assuming to that the density of tin is <span>7.31 g/cm^3, you can change it it is not the number. Below is the solution. I hope it helps.
</span><span>95.04g x (1 cm³ / 7.31g) = 13.0 cm³</span>
Taking into account the definition of density, the density of the sample is 0.5
.
It is necessary yo 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 allows you to measure the amount of mass in a certain volume of a substance.
Then, 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:
Then, replacing in the definition of density:

Solving:
<u><em>density= 0.5 </em></u>
<u><em /></u>
Finally, the density of the sample is 0.5
.
