Answer: -
The density of the object is (d) 1.39 g / mL
Explanation: -
The mass of an object is given as 19.5 g.
The volume of the object is 14.0 mL.
We are given the formula for density.
The given formula is
Density = [tex] \frac{Mass}{Volume} [/tex]
Plugging in the supplied values we get
Density = [tex] \frac{19.5 g}{14.0 mL} [/tex]
= 1.39 g/ mL
The answer is correct to 3 significant figures.
Thus the correct option is d.
