Question

How many liters of ammonia (NH3) are contained in 800 ml of a solution that is 12% ammonia by volume?

Answer 1

Solution:

Percent by volume = (Volume of the solute / Volume of the solution) × 100%

solute = NH₃

Therefore,

12% = (Volume of NH₃ / 0.8 L) × 100%

Volume of NH₃ / 0.8 L = 0.12

Volume of NH₃ = 0.12 × 0.8 L = 0.096 L

Volume of NH₃ = 0.096 L

Answer: 0.096 liters of ammonia (NH₃)
