Determine the density of an object that has a mass of 149.8 g and displaces 12.1 mL of water when placed in a graduated cylinder
Crazy boy [7]

Answer:

"12.4 g/mL" would be the right solution.

Explanation:

The given values are:

Mass of the object,

= 149.8 g

Volume of the object,

= 12.1 mL

Now,

The Density will be:

⇒ Density=\frac{Mass}{Volume}

On substituting the given values in the above formula, we get

⇒               =\frac{149.8}{12.1}

⇒               =12.4 \ g/mL
