A large piece of jewelry has a mass of 130.8 g. A graduated cylinder initially contains 47.7 mL water. When the jewelry is submerged in the graduated cylinder, the total volume increases to 62.4 mL. (a) Determine the density (in g/cm3) of this piece of jewelry. g/cm3

Respuesta :

Answer: The density of this piece of jewelry is [tex]8.90g/cm^3[/tex]

Explanation:

To calculate the density, we use the equation:

[tex]\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}[/tex]

Mass of piece of jewellery = 130.8 g

Density of piece of jewellery = ?

Volume of piece of jewellery =( 62.4-47.7 ) ml = 14.7 ml = [tex]14.7cm^3[/tex]   [tex]1cm^3=1ml[/tex]

Putting values in above equation, we get:

[tex]\text{Density of piece of jewellery}=\frac{130.8g}{14.7cm^3}=8.90g/cm^3[/tex]

Thus density of this piece of jewelry is [tex]8.90g/cm^3[/tex]
