Problem

An entomologist caught a "mol" and he wants to dry it. Calculate its mass after evaporation of all the water, if you know that a particular ball of one mole of living "mols" • contains n=3.346⋅1019n = 3.346·10^{19} mol of water molecules, • has surface area equal to twenty four times the area of Moldova (including Transnistria), • has density ρ=27.4ρ = 27.4 kg·m⁻³. Translator's note: "mol" is a Czech word for a clothing moth.
