What volume of 0.0305 M EDTA is needed to titrate the Ca in 178.56 mg of CaCO3?

Solution:

If CaCO3 sample is titrated with EDTA disodium salt solution, then the chemical reaction is 


Therefore, from the chemical reaction above, the volume of EDTA disodium salt solution to titrate CaCO3 sample is
