Mercury is a liquid metal having a density of 13.6 gml what is the volume of 1.00 lb of mercury metal

tresset_1 [31]

The volume of 1.00 lb of mercury metal : 33.352 ml

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

Density formula:

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density

m = mass

v = volume

Density of metal(mercury) = 13.6 g/ml

mass of mercury : 1 lb = 453,592 g

So the volume :

$\tt V=\dfrac{453,592~g}{13.6~g/ml}\\\\V=33.352~ml$
