Question

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

1 Answer

  • Answer

    The density of ring is  2 g/ml .

    Option (A) is correct.

    Explanation :

    Formula

    [tex]Density = \frac{Mass}{Volume}[/tex]

    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

    [tex]Density = \frac{5}{2.5}[/tex]

    [tex]Density = \frac{50}{25}[/tex]

    Density = 2 g / ml

    Therefore the density of ring is  2 g/ml .

    Option (A) is correct .
