What is the mass of a pure platinum disk with a volume of [tex]113 \, \text{cm}^3[/tex]? The density of platinum is [tex]21.4 \, \text{g/cm}^3[/tex].

Give your answer in grams and kilograms.

Multiply the density with the volume. You get 2418.2 grams or 2.4182 kilograms :)

The **mass **of the platinum if the **volume **is 113 cm³ and density is 21.4 g / cm³ is 2.418 kilograms or 2 **kilograms **and 418 grams .
What is density?
The density is the mass of a material substance per unit volume . d = M/V, where d is density, M is mass , and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density .
As an illustration, the density of Earth is 5.51 grams per cubic centimeter, whereas the density of water is 1 gram per cubic centimeter.
Given :
The volume of the platinum disk, V = 113 cm³,
The density of platinum, d = 21.4 g / cm³
Calculate the mass using density and mass relation as shown below,
density = Mass of the platinum / Volume of the platinum
21.4 = Mass of the platinum / 113
Mass of the platinum = 21.4 × 113
Mass of the platinum = 2418.2 g
As we know 1 kg = 1000 grams,
Mass of the platinum = 2418.2 / 1000
Mass of the platinum = 2.418 kg
Thus, the mass of the platinum is 2.418 kg.

The mass of the pure platinum disk with a volume of 113 cm³ and a density of 21.4 g/cm³ is calculated to be 2423.2 grams or approximately 2.423 kilograms. This was determined using the formula mass = density × volume. The result shows how mass is derived from both density and volume measurements.
