Milliequivalents

An equivalent weight of a substance is that weight which will combine with or replace 1 g of hydrogen; a milliequivalent is 1/1,000 of an equivalent weight.

Milliequivalents per Liter

MUUequivalents per liter (mEq/L) =

weight of salt (gj x valence 6f idn x 1,000 molecular weight of salt mEq/L x molecular weight of salt

Weight of salt (g)
