what you would do to prepare 100.0g of a 3.5% solution of ammonium sulfate in water
Dissolve 3.50 g (NH4)2SO4 in some water and make to a final weight of 100.0
Well, preparing a 3.5% solution of ammonium sulfate in water sounds like a piece of cake! Here's what I would do:
1. First, grab a container and put on your chef hat!
2. Measure out 3.5 grams of ammonium sulfate. (Don't worry, I won't tell anyone if you use a scale.)
3. Add the measured ammonium sulfate to the container. Think of it as cooking up some chemistry.
4. Now, it's time to add water to the mix. Start pouring water into the container while stirring like a mad scientist.
5. Keep adding water until you have a total mass of 100.0 grams of solution. Just remember to keep stirring! You don't want any lumpy surprises.
6. Voila! You have now successfully prepared a 3.5% solution of ammonium sulfate in water. Give yourself a round of applause!
Remember, laughing makes science way more fun. Just be sure to wear your safety goggles while you're at it!
To prepare a 3.5% solution of ammonium sulfate in water, you will need to follow these steps:
Step 1: Calculate the mass of ammonium sulfate needed:
- Mass of solution = 100.0g
- Percentage concentration = 3.5%
- Mass of ammonium sulfate = (3.5/100) x 100.0g
= 3.5g
Step 2: Measure out 3.5g of ammonium sulfate using a precise balance or scale.
Step 3: Add the measured 3.5g of ammonium sulfate into a container.
Step 4: Add some distilled water into the container. Adding it slowly while stirring will help dissolve the ammonium sulfate more easily.
Step 5: Continue adding distilled water until the total mass of the solution reaches 100.0g.
Step 6: Stir the solution thoroughly until all of the ammonium sulfate has dissolved.
And that's it! You have now prepared a 3.5% solution of ammonium sulfate in water.
To prepare a 100.0g solution of ammonium sulfate in water with a concentration of 3.5%, you would need to follow these steps:
Step 1: Calculate the mass of ammonium sulfate required.
Since you want the final solution to have a mass of 100.0g, and the concentration is 3.5%, you can use the relationship: mass = concentration × volume.
First, convert the concentration to a decimal: 3.5% = 3.5/100 = 0.035.
Then, calculate the mass of ammonium sulfate needed: mass = 0.035 × 100.0g = 3.5g.
Therefore, you would need 3.5g of ammonium sulfate.
Step 2: Dissolve the ammonium sulfate in water.
Take the calculated mass of ammonium sulfate (3.5g) and add it to an appropriate amount of water in a container. Ensure that the container is large enough to hold both the ammonium sulfate and the water.
Step 3: Stir or mix the solution.
Use a stirring rod or gently swirl the container to dissolve the ammonium sulfate in water thoroughly. Continue stirring until all the solid has dissolved completely.
Step 4: Add additional water, if needed.
Check the total mass of the solution. If it is below 100.0g, add additional water to reach the desired final mass. Stir again to ensure uniformity.
Note: It is important to handle chemicals safely, wear appropriate protective gear, and follow any specific lab procedures or protocols when working with substances like ammonium sulfate.
