A solution of ammonia (NH3) in water is 45.3% by mass ammonia. What is the concentration of ammonia expressed, assuming the density of the solution is 1 g/mL? a. Molarity b. Molality c. Mole fraction
Added by Donna C.
Step 1
Given: - Mass of ammonia (NH3) = 45.3 g - Density of the solution = 1 g/mL - Volume of the solution = 100 mL = 100 g Molarity = (Mass of solute / Molar mass of solute) / Volume of solution in liters Molar mass of ammonia (NH3) = 17 g/mol Molarity = (45.3 g / 17 Show more…

A bottle of concentrated aqueous ammonia is labelled " $29.8 \% \mathrm{NH}_{3}$ by mass; density $=0.8960 \mathrm{~g} / \mathrm{mL}$." (a) What is the molarity of the ammonia solution? (b) If $300.0 \mathrm{~mL}$ of the commercial ammonia is diluted with water to make $2.50 \mathrm{~L}$ of solution, what is the molarity of the diluted solution?
Calculate the volume of concentrated ammonia solution, which is 15 molar, that contains 75.0 g of ammonia.
