24-hr urine specimen was diluted to 2.000 L. After the solution was buffered to pH 10, a 10.00-mL aliquot was titrated with 23.57 mL of 0.004590 M EDTA. The calcium in a second 10.00-mL aliquot was isolated as CaC₂O₄(s), redissolved in acid, and titrated with 10.53 mL of the EDTA solution. Calculate the mass of Mg in the sample. Calculate the mass of Ca in the sample
