Calculation of mass and moles of Mg2+???
« on: July 01, 2010, 02:54:30 AM »
Mass of Magnesium Salt: 0.1466g
Volume of EDTA used: 33.6mL
EDTA=0.01013 M

How do I calculate the moles of Mg2+? The Mass of Mg2+ in the Magnesium sample? The formula weight of MgO? And the Mg2+ as % MgO with 95% confidence interval?

If you can help me solve ANY of these questions, it would be of much help to me!!!
