Capitolo 4, Problema 61a
(a) Calculate the molarity of a solution that contains 0.175 mol ZnCl2 in exactly 150 mL of solution.
Guida verificata passo dopo passo1
Understand that molarity (M) is defined as the number of moles of solute divided by the volume of solution in liters. The formula is: M = \( \frac{\text{moles of solute}}{\text{liters of solution}} \).
Identify the given values: 0.175 moles of ZnCl2 and 150 mL of solution.
Convert the volume from milliliters to liters, since molarity requires the volume in liters. Use the conversion: 1 L = 1000 mL. Therefore, 150 mL = 0.150 L.
Substitute the values into the molarity formula: M = \( \frac{0.175 \text{ mol}}{0.150 \text{ L}} \).
Perform the division to find the molarity of the ZnCl2 solution.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
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). To calculate molarity, one must know the amount of solute in moles and the total volume of the solution in liters.

Molarity
Conversion of Volume Units
In chemistry, it is often necessary to convert volume measurements to liters when calculating molarity. Since 1 liter equals 1000 milliliters, to convert milliliters to liters, one divides the volume in milliliters by 1000. This conversion is crucial for accurate molarity calculations.
