Calculate the molarity of each solution.
a. 3.25 mol of LiCl in 2.78 L solution
b. 28.33 g C₆H₁₂O₆ in 1.28 L of solution

검증된 단계별 안내

Identify the formula for molarity: \( M = \frac{\text{moles of solute}}{\text{liters of solution}} \).

Determine the number of moles of solute, which is given as 3.25 mol of LiCl.

Determine the volume of the solution in liters, which is given as 2.78 L.

Substitute the values into the molarity formula: \( M = \frac{3.25 \text{ mol}}{2.78 \text{ L}} \).

Simplify the expression to find the molarity of the solution.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Molarity

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. It is expressed in units of moles per liter (mol/L). Molarity is crucial for understanding how concentrated a solution is and is commonly used in chemistry to prepare solutions and perform stoichiometric calculations.

Moles

A mole is a fundamental unit in chemistry that quantifies the amount of substance. One mole corresponds to approximately 6.022 x 10²³ entities, such as atoms or molecules. Understanding moles is essential for converting between mass and number of particles, which is necessary for calculating molarity.

Volume of Solution

The volume of a solution is the total space that the solution occupies, typically measured in liters (L) or milliliters (mL). In molarity calculations, the volume of the solution is critical as it serves as the denominator in the molarity formula, directly affecting the concentration of the solute in the solution.
