Which of the following expressions is correct?

Options

A. `N=(meq)/L`
B. `N=(meq)/(mL)`
C. `N=(mmol)/("molar mass")`
D. `N=(meq)/(mg//meq)`

Answer

2

Explanation

Normality of a solution is defined as the number of equivalents of solute per litre of solution. By definition, there are 1000 milliequivalents (meq) in one equivalent of so,ute and 1000 milliliters in one litre of solution. Thus, normality may also be repersented as
`Normality=("Number of milliequivalents of solute")/("Millilitres of solution")`
`=(no . meq)/(mL)`
