Jenny accidentally drops her ring into a graduated cylinder. If the ring has a mass of 5 grams and the water level in the cylinder
rises from 5 mito 7.5 ml, determine the density of the ring.

A: 2 g/mi

B: 50 g/mi

C: 15 g/mi

D: 0.5 g/mi

Respuesta :

Answer:

A. δ = 2 g/mi

Explanation:

  • density ( δ ) ≡ mass ( m ) / volume ( v )

∴ mass ( m ) = 5 g

∵ Δv = 7.5 mL - 5 mi = 2.5 mi

⇒ δ =  5 g / 2.5 mi

⇒ δ = 2 g/mi
