Question

If you have a graduated cylinder, containing 15.5 mL and this volume changes to 95.2 mL after a metal with a mass of 7.95g is dropped into the graduated cylinder then what is the density of this metal?

(A) 0.0835 g/mL
(B) 0.513 g/mL
(C) 0.0718 g/mL
(D) 10.0 g/mL
(E) 9.97 x10^-2 g/mL

Answer 1

Answer: The density of the object will be
`9.97* 10^(-2)` g/ml.

Step-by-step explanation:

Density is defined as the mass contained per unit volume.

`Density=(mass)/(Volume)`

Given : Mass of object = 7.95 grams

Volume of water displaced = volume of the object = (95.2 - 15.5) ml =79.7 ml

Putting in the values we get:

`Density=(7.95g)/(79.7ml)=0.0997g/ml`

Thus density of the object will be
`9.97* 10^(-2)` g/ml
