average : 13.69mL
calculate total moles of Mg2+ AND CA2+ in 10mL hard water
option 1: 13.65/1000=0.001365L x 0.01 M EDTA= 1.365x10^-5
or
option 2: the same as above but include my calcium moles
and multiple it by my Ca2+ moles?

Hmm... to no longer sound impolite, yet i've got self belief you'll be able to nicely be lacking some suggestions right here. often in stoicheometry (mole conversions), there's a particular weight, often in grams, of substance you're changing. How plenty CaCO3 do you have?
