34. JAnswer this: Pure (24 carat) gold has a density of 19 g/mL. If you bought"gold" ring and found it had a volume of 0.3 ml and that it weighed 5.7 grams, is it pure gold? Show your work to support your answer.​

Respuesta :

Explanation:

Density = mass / volume

ρ = 5.7 g / 0.3 mL

ρ = 19 g/mL

Yes, it's pure gold.

Yes, it's pure gold.

How do you calculate gold density?

  • The mass of an object divided by its volume is the formula for determining density.
  • This is expressed mathematically as d = m/v, where d denotes density, m denotes mass, and v denotes object volume.
  • The common measurements are kg/m³.

What is the formula of volume?

  • The basic formula for volume is length, breadth, and height, as opposed to length, width, and height for the area of a rectangular shape.

What is the volume of pure gold?

  • Gold has a specific gravity of 19.3.
  • In light of this, 19.3 grams take up 1 cubic centimeter. 31.1 grams make up a Troy ounce.
  • As a result, we need 31.1/19.3 = 1.61 cubic centimeters to equal 1 Troy Oz.

According to the question:

Density = mass / volume.

ρ = 5.7 g / 0.3 mL.

ρ = 19 g/mL.
