Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder weighs 40,500 mg. Calculate the density of mercury.

Therefore, the density of mercury is 1.8g/mol

Explanation:

To calculate the density of a substance, we use the equation:

Density = mass / volume

we are given,

Mass of mercury = 40,500 mg = 40.5g

Volume of mercury = 22.5 mL

inserting the values in the equation

density of mercury =  40.5g / 22.5 mL

density of mercury = 1.8g/mol

Therefore, the density of mercury is 1.8g/mol
