Calculate the sodium (Na+) content, in terms of milliequivalents, of 1 g of ampicillin sodium (C16 H18 N3 NaO4 S—m.w. 371).
answer ;2.7 mEq
Miliequivalent = mg / equivalent weight
Equivalent weight = molecular weight / valence
Valence of sodium is 1
Molecular weight as given in question is 371
Equivalent weight = 371
Ampicillin sodium = 1gm or 1000mg
Milliequivalent = 1000/371 = 2.69 or 2.7mEq
