Answer : The original concentration of copper (II) sulfate in the sample is,
Explanation :
Molar mass of Cu = 63.5 g/mol
First we have to calculate the number of moles of Cu.
Number of moles of Cu =
Now we have to calculate the number of moles of
Number of moles of Cu = Number of moles of
Number of moles of =
Now we have to calculate the molarity of
Now put all the given values in this formula, we get:
To change mol/L into g/L, we need to multiply it with molar mass of
Molar mass of = 159.609 g/mL
Concentration in g/L =
Thus, the original concentration of copper (II) sulfate in the sample is,
