Question

A brass ornament has a volume of 24 cm³. Brass has a density of 8.7g/cm³. Find the mass of the brass ornament

Answer 1

Step-by-step explanation:

volume given 24cm^3

density given 8.7g/cm^3

then d=m/v so, mass m = d ×v = 24×8.7=208.8g

Answer 2

Answer: 208.8 g

Step-by-step explanation:

• We know density is the amount of matter contained in a body so if a body has a certain volume and we know its mass then we can calculate the density of the material in the body by the formulae given below.

$Density=\frac{Mass}{Volume}$

• Given: Volume=24 $cm^{3}$ and density= 8.7 gm/$cm^{3}$.
• Now by using the above formulae we can easily calculate the mass of the ornament.
• Solution:

   $Density=\frac{Mass}{Volume}$

⇒ $8.7=\frac{Mass}{24}$

⇒$Mass=24*8.7$

∴ Mass=208.8 g

• Hence, the required mass of the ornament is 208.8 g.
