Question:
Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder weighs 306.0 g. From this information, calculate the density of mercury.
Density of a substance:
In simple terms, it is the ratio of the body's mass to the volume of a body. It is the measure of how densely its mass is occupied in a volume of a body. It is measured in kg/m3kg/m3 , gm/cm3gm/cm3, gm/mlgm/ml, or kg/lkg/l.
Answer and Explanation:
Volume of graduated cylinder, V=22.5 mL
Weight of mercury, M= 306 g
Density is calculated mathematically by the expression
Density, ρ=MV........(1)ρ=MV........(1)
Where,
M= Mass of the body
V=Volume of the body
Substituting the value of mass and volume in equation (1)
ρ=30622.5ρ=13.6g/mLρ=30622.5ρ=13.6g/mL
Thus, the density of mercury weighing 306 g and occupying a 22.5 mL volume is 13.6 g/mL.
