Answer:

The physical properties of a solution are different from those of the pure solvent. ... Colligative properties are those physical properties of solutions of nonvolatile solutes that depend only on the number of particles present in a given amount of solution, not on the nature of those particles.

Which of the following best describes solids?
Angelina_Jolie [31]
In my opinion I would pick D. 

Multiple answers could be chosen, just due to the fact that a solid is nothing more than just an object that cannot change it's physical shape into an object; just as water would. a solid can have a low density; such as paper, plastics, or even just a piece of wood. 

But think of a block of ice. You can break it, and crush it. It cannot be formed into any other shape. If you did break it, it only would make more ice fragments. And it's next phase is a liquid; if it were to be melted.

What is the mass in milligrams of 4.30 moles of sodium? use significant figures?
alexandr1967 [171]
Answer is: mass <span>of 4,30 moles of sodium</span> is 98800 mg.
n(Na) = 4,30 mol.
m(Na) = ?
m(Na) = n(Na) · M(Na).
m(Na) = 4,30 mol · 23 g/mol.
m(Na) = 98,90 g.
m(Na) = 98,90 g · 1000 mg/1g.
m(Na) = 98900 mg.
n - amount of substance.
m - mass of substance.
M - molar mass of substance.
