can you help me and line it exactly like this because i keep doing it and its says its wrong

How can we find the volume for both questions?

Part of a buret measuring in mL is shown below. Read the volume to the proper number of significant digits. 45 46 Volume mL 47 48 49 2. Suppose it takes 33.69 mL of 0.005123 M EDTA to titrate 25.00 mL of a hard water solution. a) How many moles of EDTA were required to titrate to the endpoint? b) How many moles of hard water ions, expressed as moles of Ca?+, are present in the hard water solution? c) What is the concentration, expressed as molarity of Ca2+, of hard water ions in the solution? d) If the metal ions in the hard water all came from CaCO3, how many grams of CaCO3 would be in 1.000 L of the solution (in other words, determine g CaCO3/L)? e) Convert g CaCO3/L calculated in (d) to mg CaCO3/L. (This is equivalent to ppm.)
