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 ml to 7.5 ml, determine the density of the ring. a) 2 g/ml b) 50 g/ml c) 15 g/ml d) 0.5 g/ml

Answer

The density of ring is  2 g/ml .

Option (A) is correct.

Explanation :

Formula

As given

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 ml to 7.5 ml .

Mass = 5 gram

Volume = Rise in volume - Initial volume

( Rise in volume = 7.5 ml , Initial volume = 5 ml)

Volume = 7.5 ml - 5 ml

              = 2.5 ml

Putting the values in the formula

Density = 2 g / ml

Therefore the density of ring is  2 g/ml .

Option (A) is correct .
