Answer: For your first question about the book, the answer is 6 g/cm^3. For the ball, your mass is 50 grams.
Explanation: density = mass/volume; for example: your book was 1,800 g. Divide that by 300 cm^3 to get 6g/cm^3. For the ball, mass = density*volume, so you need to multiply .250 by 200 cm^3
Answer : The density of book is [tex]6g/cm^3[/tex]
The mass of a ball is, 50 grams.
Explanation :
Part 1 :
Density : It is defined as the mass contained per unit volume.
Formula used :
[tex]Density=\frac{Mass}{Volume}[/tex]
Given :
Mass = 1800 g
Volume = [tex]300cm^3[/tex]
Now put all the given values in the above formula, we get :
[tex]Density=\frac{1800g}{300cm^3}=6g/cm^3[/tex]
Therefore, the density of book is [tex]6g/cm^3[/tex]
Part 2 :
Formula used :
[tex]Density=\frac{Mass}{Volume}[/tex]
Given :
Volume = [tex]200cm^3[/tex]
Density = [tex]0.250g/cm^3[/tex]
Now put all the given values in the above formula, we get :
[tex]0.250g/cm^3=\frac{Mass}{200cm^3}[/tex]
[tex]Mass=0.250g/cm^3\times 200cm^3=50g[/tex]
Therefore, the mass of a ball is 50 grams.
