Answer:

Evaporation - vaporization that occurs at the surface of a liquid

Freezing - the process by which a liquid becomes a solid

Boiling - vaporization that occurs below the surface of a liquid

Melting - the process by which a solid becomes a liquid

Sublimation - the process by which a solid becomes a gas

Hope this helps!

A student weighs out a 7.24 g sample of , transfers it to a 300. mL volumetric flask, adds enough water to dissolve it and then

velikii [3]

The molarity of the zinc chloride solution will be 0.089 M

<h3>Molarity</h3>

Mole of 7.24 g ZnCl2 = 7.24/136.286 = 0.5312 mol

Total volume of water used in preparing the solution = 300 + 300 = 600 mL

Molarity of the solution = mole/volume = 0.5312/0.6 = 0.089 M

The molarity of the zinc chloride solution is, therefore, 0.089 M
