What volume of 0.200 M ethanol solution contains each amount in moles of ethanol? a. 0.45 mol ethanol

Guida verificata passo dopo passo
1
Determine the relationship between molarity, moles, and volume using the formula: Molarity (M) = \(\frac{moles}{volume (L)}\).
Rearrange the formula to solve for volume: Volume (L) = \(\frac{moles}{Molarity (M)}\).
Substitute the given values into the equation: moles = 0.45 mol and Molarity = 0.200 M.
Calculate the volume in liters using the rearranged formula.
Convert the volume from liters to milliliters if needed, using the conversion factor: 1 L = 1000 mL.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Molarity

Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution. It is expressed in moles per liter (mol/L) and is crucial for calculating how much solute is present in a given volume of solution. Understanding molarity allows one to relate the amount of solute to the volume of the solution, which is essential for solving concentration-related problems.

Volume Calculation

To find the volume of a solution needed to contain a specific number of moles of solute, the formula used is Volume (L) = Moles of solute / Molarity. This relationship allows for the direct calculation of the required volume when the amount of solute and its concentration are known. It is a fundamental concept in stoichiometry and solution preparation.

Stoichiometry

Stoichiometry is the area of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It involves using balanced chemical equations to calculate the amounts of substances involved. In the context of solutions, stoichiometry helps in determining how much of a reactant is needed or produced, based on the concentrations and volumes of solutions.
