Harry's Golden Snitch, the smallest ball in Quidditch, is a sphere with a radius of 3.10 cm and a density of 6.12 g/cm³. What is its mass? Express your answer in grams.

Answer :

Final answer:

The mass of Harry's Golden Snitch is approximately 839.31 grams.

Explanation:

To find the mass of Harry's Golden Snitch, we can use the formula for the volume of a sphere: V = (4/3)πR³. With a radius of 3.10 cm, we can calculate the volume of the sphere to be approximately 137.13 cm³. Since the density of the Snitch is given as 6.12 g/cm³, we can use the formula density = mass/volume to find the mass. Rearranging the formula, we get mass = density * volume. Substituting the values, we find the mass to be approximately 839.31 grams.
