What is the molar concentration of calcium in the unknown

A sol. of unknown Calcium concentration is titrated using EDTA. The EDTA is first standardized against a primary standard Zinc sol. prepared by dissolving 0.4088g of Zn in 1.000L of sol. A 20.00mL aliquot of the Zn sol. required 31.06 mL of EDTA sol. to titrate to endpoint. A 25.00mL aliquot of the calcium unknown requited 46.77mL of the EDTA to titrate to endpoint. What is the molar concentration of calcium in the unknown sample?
