Question

How many milliequivalents of potassium would be supplied daily by the usual dose (0.3 mL three times a day) of saturated potassium iodide solution? Saturated potassium iodide solution contains 100 g of potassium iodide per 100 mL.

Answer 1

Ans :

The amount of dose delivered daily = 0.3 mL x 3 = 0.9 mL

The concentration of the solution is 100 g / 100 mL

So 0.9 mL of its solution will contain : ( 0.9 x 100) / 100 = 0.9 g of potassium iodide

1 equivalent of KI weighs = 166.0028 g/mol

So number of equivalents of KI in 0.9 g will be : ( 0.9 / 166.0028)

= 0.00542 equivalents

this is equal to the number of equivalents of potassium too

Number of milliequivalents = 0.00542 x 1000

= 5.42 milliequivalents
