<u>Answer:</u> The concentration of solution is 0.342 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Mass of solute (Sodium chloride) = 15 g
Molar mass of sodium chloride = 58.5 g/mol
Volume of solution = 750 mL
Putting values in above equation, we get:
Hence, the concentration of solution is 0.342 M

Answer:
Periods on the periodic table of elements
Explanation:
In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. (See also The Periodic Table: Metals, Nonmetals, and Metalloids.) In each period (horizontal row), the atomic numbers increase from left to right.

Answer:</h3>
Homogeneous mixture with components of different boiling points
<h3>
Explanation:</h3>
- Distillation is a method of separating miscible mixtures which contain components that have different boiling points.
- The mixture is heated and the component with the low boiling point evaporates first. It is then condensed in the condenser and the distillate collected using a clean beaker.
- For example, a miscible solution of ethanol and water can be separated using distillation.
- Ethanol and water have different boiling points of 78°C and 100°C respectively. Ethanol is distilled out first because it has a low boiling point compared to water.
