Chemistry Fun: Calculating Percentage Mass of Ammonia in Household Cleaner!
Have you ever wondered how to calculate the percentage mass of ammonia in a household cleaner? Well, it's actually quite simple! By using the given data and a bit of chemistry knowledge, we can easily determine the percentage mass of ammonia in the cleaner. Let's break it down step by step:
Step 1: Calculate the number of moles of H₂SO₄ used
To start off, we need to determine the number of moles of sulphuric acid (H₂SO₄) used in the neutralization reaction. By calculating the moles of H₂SO₄, we can then find the moles of NH₄OH used in the reaction as well.
Step 2: Calculate the molar mass of NH₄OH
Next, we find the molar mass of ammonium hydroxide (NH₄OH) by adding up the atomic masses of nitrogen (N), hydrogen (H), and oxygen (O) in the compound.
Step 3: Calculate the mass of NH₄OH used
Once we have the moles of NH₄OH, we can determine the mass of NH₄OH used in the reaction by multiplying the moles with the molar mass.
Step 4: Calculate the percentage mass of NH₃ in the cleaner
Finally, we calculate the percentage mass of ammonia (NH₃) in the household cleaner by considering the mass of ammonia compared to the total mass of the cleaner. This gives us the final result of approximately 16.9%.
So, there you have it! By following these simple steps and using some basic chemistry principles, we can calculate the percentage mass of ammonia in a household cleaner. Chemistry can be fun and useful in solving everyday problems like these!
