Phase is not determined by the number of molecules, as a substance with any number of molecules can be either solid, liquid, or gas.
Arrangement of molecules and molecular structure matter, since solids are closely packed together, gases are not, and liquids are in between. Intermolecular forces are also stronger for solids and liquids than they are for gases.
Answer:
B. It contains 15.0 grams of HNO₃ per 100 grams of solution.
Explanation:
- The percent of a solute in a solution is the mass of the solute (g) per 100 g of solution.
<em>So, an aqueous solution that is 15.0 percent HNO₃ by mass means that It contains 15.0 grams of HNO₃ per 100 grams of solution.</em>
Minerals need to be solid with a crystalline structure. Ice has these properties, liquid water does not. (i hope that helps you)
