Question

A student is investigating the effect of concentration on the colour of a solution of copper sulfate.She wished to make up 250cm^3 of a solution if copper sulfate with a concentration of 0.5 mol/dm^3 that she can dilute. a solution with the concentration of 0.50 mol/dm^3 contains 0.50 mol of copper sulfate per decimetre cubed calculate the concentration of this solutionin g/dm^3

    Answer:

    79.8g/dm³

    Explanation:

    As you can see, the solution in the problem contains 0.5 moles of copper sulfate per dm³. To solve this question we must convert these moles to grams using its molar mass (Molar mass CuSO4 = 159.609g/mol) as follows:

    0.5mol CuSO4/dm³ * (159.609g/mol) =

    79.8g/dm³
