A 20-mL vial of concentrated ammonium chloride solution containing 5 mEq/mL

is diluted to 1 liter with sterile distilled water. Calculate
(a) the total milliequivalent value of the ammonium ion in the dilution and
(b) the percentage strength of the dilution.

(a) The total milliequivalent value of the ammonium ion in the dilution is 5,000 mEq.

(b) The percentage strength of the dilution is 0.5%.
