how to add .01g grams of CaCO3 to a 2mL microcenterfudge tube?
Homework Answers
The microcentrifuge tube is too narrow to add CaCO3 directly. Therefore it is adviced to first dissolve the CaCO3 weighed out by you in the medium that you will be centrifuging before adding it to the tube.

Calculate the grams of CaCO3 assuming a 1:1 molar ratio between EDTA and CaCO3. Use the average moles of Ca2+ from all 3 trails (tap water) to calculate the grams. This is the equation he wants us to use: (moles of Ca2+) (1mol CaCO3/1mol Ca2+) (100.1g/1molCaCO3) Average was: 0.074203 moles Ca2+ from all 3 trials Then the answer from that we have to figure out parts per million of the tap water. He gave us this equation: ppm=milligrams CaCO3/Kg H2O
