Question

How many mEq of phosphate are there in 750mL of 5.25% magnesium phosphate? 1000 mEq = 1 mol 1mol magnesium phosphate = 263 g magnesium phosphate

Answer 1

mass of magnesium phosphate = 5.25 g

moles of magnesium phosphate = 5.25 / 263

                                                  = 0.01996 mol

moles of phosphate = 0.03992 mol

1 mol   -------------------> 1000 mEq

0.03992 mol -------------->   ??

phosphate mEq = 39.9 mEq
