What is the volume of 100 moles of mercury?

1. Let’s write down the formula to determine the mass, through the density of the substance:
m = ρ * V, where ρ is the density of the substance, V is the volume of the substance.
According to the reference book, the density of mercury ρ = 13600 kg / m³
2. Let’s write down expressions to determine the amount of a substance:
ν = m / M, where m is the mass of the substance, M is the molar mass of the substance.
The molar mass of mercury taken from the periodic table M = 0.2 kg / mol.
Let us express the mass from this expression:
m = ν * M
Substitute this expression into the formula from paragraph 1:
ν * M = ρ * V
Let’s express the volume:
V = ν * M / ρ
3. Substitute the numerical values:
V = ν * M / ρ = 100 * 0.2 / 13600 = 0.00147 m³
Answer: mercury will occupy 0.00147 m³.
