mercury has a density of 13.6g/mol what volume of mercury must be taken to obtain 225g of the metal

16.54 mL

Explanation:

From the question;

Density of mercury of 13.6 g/mL Mass of the mercury metal is 225 g

We are needed to determine the volume of the mercury metal;

We need to know that;

Density is given by dividing the mass of a substance by its volume.

That is;

Density = Mass : Volume

Rearranging the formula;

Volume = Mass : Density

Therefore;

Volume = 225 g : 13.6 g/mL

= 16.54 mL

Thus, the volume of the mercury needed is 16.54 mL
