Asolute with a density of 1.15 g/ml and mass of 45.95 g is dissolved in 250. ml of water. what is the volume of the solute, and what is the volume percent (v/v)?

39.95 mL is the volume of the solute

13.77% is the volume percent (v/v).

Explanation:

Density of solute = 1.15 g/mL

Mass of solute = 45.95 g

Volume of the solute = V

Volume of the solvent that water = 250 mL

Volume of the solution = 250 mL + 39.95 mL = 289.95 mL

Volume percent (v/v):

39.95 mL is the volume of the solute

13.77% is the volume percent (v/v).

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.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
