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 $9.97\times 10^{-2}$ g/ml.

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

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:

$Density=\frac{7.95g}{79.7ml}=0.0997g/ml$

Thus density of the object will be $9.97\times 10^{-2}$ g/ml
