Question

Ammonium nitrate (NH₄NO₃) is a common component of fertilizer because it is a great source of two nitrogen-containing ions that easily dissolve into water. A large batch of this liquid fertilizer is made by adding 1.63 pounds of ammonium nitrate to 21.00 gallons of water. What is the molarity of this solution? (Hint: 1 lb. = 454 g and 1 gal. = 3.79 L.)

Answer 1

Molarity = $454 × 3.79=1720.66 M$
