What volume of 0.200 M ethanol solution contains each amount in moles of ethanol? c. 1.2⨉10-2 mol ethanol

Guida verificata passo dopo passo
1
Determine the relationship between moles, molarity, and volume using the formula: Molarity (M) = \( \frac{\text{moles of solute}}{\text{volume of solution in liters}} \).
Rearrange the formula to solve for volume: Volume (L) = \( \frac{\text{moles of solute}}{\text{Molarity}} \).
Substitute the given values into the equation: moles of ethanol = 1.2 \(\times\) 10^{-2} \(\text{ mol}\) and Molarity = 0.200 \(\text{ M}\).
Calculate the volume in liters using the rearranged formula.
Convert the volume from liters to milliliters if necessary, knowing that 1 L = 1000 mL.

Concetti chiave

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

Molarity (M)

Molarity 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). Understanding molarity is crucial for calculating the volume of a solution needed to achieve a specific number of moles of solute.

Molarity Concept

Volume Calculation

To find the volume of a solution required to contain a certain number of moles of solute, the formula used is Volume (L) = Moles of solute / Molarity. This relationship allows for the determination of how much solution is needed based on its concentration and the desired amount of solute.
