Silver has a density of 10.5g/cm to the 3rd and gold has density of 9.3g/cm to the 3rd. Which would have a greater mass, 5cm to the third of silver or 5cm to the 3rd of gold?

Respuesta :

The density of gold is 19.3 g/cm³

Ag= silver
Au= gold.
density (Ag)=10.5 g/cm³.
density (Au)=19.3 g/cm³

We have to calculate the mass of 5 cm³ silver:

10.5 g---------------------1 cm³
x---------------------------  5 cm³

x=(10.5 g  * 5 cm³) / 1cm³ ≈52.5 g

And we have to calculate the mass of 5 g gold.

19.3 g------------------------1 cm³
x-------------------------------5 cm³

x=(19.3 g * 5 cm³) / 1cm³≈96.5  g

Then 5 cm³ silver are 52.5 g of mass, and 5 cm³ gold are 96.5 g of mass, therefore,  gold would have a greater mass than silver.

answer:5 cm³ gold would have a greater mass than 5 cm³ silver.
