When charging a conductor by induction, a charged object is brought close to but does not touch the conductor. In the end the conductor has charge of the opposite sign as the charge on the object.

Density is mass over volume. The density of iron is given in g/cm³
we have to first convert g/cm³ to kg/dL.
1000 g = 1 kg and 100 cm³ = 1 dL
the mass of 1 cm³ = 1 g
the mass of 100 cm³ / 1 dL = 100 g
then mass of 1 dL in kg is = 100 g / 1000 g/kg = 0.1 kg
volume of 0.1 kg is 1 dL
therefore density of iron is 7.86 g/cm³ x 0.1 kg/dL / g/cm³ = 0.786 kg/dL
volume of iron having mass 0.786 kg is 1 dL
then volume of iron having a mass of 4.62 kg is - 1 dL / 0.786 kg x 4.62 kg = dL
volume of iron is 5.88 dL
Water is the universals solvent and the compound that wouldnt disolve is oli because water and oil don't mix
