Question

A chemist prepares a solution of copper(II) sulfate CuSO₄, transcription available belowby measuring out 53. g of copper(II) sulfate into a volumetric flask and filling the flask to the mark with water.

Calculate the concentration in mol/L of the chemist's copper(II) sulfate solution.

Answer 1

To calculate the concentration of a copper(II) sulfate solution, divide the mass of CuSO4 by its molar mass to get moles, then divide moles by the solution volume in liters. Without the flask's volume, the calculation cannot be completed.

Step-by-step explanation:

The student is asking how to calculate the concentration in moles per liter (mol/L) of a copper(II) sulfate (CuSO4) solution. To calculate this, we use the molar mass of copper(II) sulfate, which is 159.62 g/mol.

To find the number of moles of CuSO4, we divide the mass of the solute (53.0 g) by its molar mass:

Number of moles = 53.0 g / 159.62 g/mol = 0.332 moles

The student has not provided the volume of the volumetric flask, so I will use V as a placeholder for the volume in liters (L). The concentration is then calculated by dividing the number of moles of solute by the volume of the solution:

Concentration (M) = Number of moles / V (L)

Note that without the actual volume of the flask provided, we cannot finalize the calculation.
