You are asked to determine the amounts of calcium ion in a 200 mL water sample using EDTA to titrate the sample. It took 45.5 mL of 0.3 M EDTA to reach endpoint. What is the mass (in grams) of calcium ion in the water sample? Hint: Find out moles of EDTA used to reach endpoint, relate to mol of calcium ion, convert mol of calcium to gram of calcium. The molar mass of Ca is 40.08 g/mol. Round and report your answer to the SECOND decimal place. Numeric value only, no unit.
