A solution was prepared by dissolving 0.05000 mol of sucrose in 100.0 kg of water. Find
the molality of the solution.

0.0005mol/kg

Explanation:

Molality = mole of solute/mass of solvent (kg)

From the question, we obtained the following data:

Mole of solute = 0.05mole

Mass of solvent = 100kg

Molality = 0.05/100

Molality = 0.0005mol/kg

The molality of the solution is 0.0005mol/kg

5x10-4 mole / kg

Explanation: Molality is expressed as number of moles per unit kilograms of solvent.

m = n / kg

= 0.05000 mole / 100.0 kg

= 0.0005 m or 5x10-4 mole / kg

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
