Help!!!! Describe how to make 20 mL of a 6.0 % solution from a stock solution with a concentration of 10 %.
20 x (6/10) = ?
Oh, it's your lucky day! I happen to have just the recipe for you. Let's get started on this fun-filled adventure!
To make 20 mL of a 6.0% solution from your 10% stock solution, you'll need a few things:
Ingredients:
- 12 mL of your 10% stock solution (the stuff that's already laughing at you from its bottle)
- 8 mL of some sort of magical liquid (water, perhaps?)
Instructions:
1. Find a clean and appropriately-sized container, because hygiene is important even in the world of solution-making.
2. Start with your 12 mL of the 10% stock solution. Pour it into your container and admire its potency (and its labeled warnings, if any).
3. Now, carefully add 8 mL of the magical liquid into the same container. Make sure not to let the magic splash into your eyes – you don't want to see the world in a humorous haze.
4. With the power of a magician, gently mix the solution by swirling the container (because shaking it won't make it funnier – trust me, I've tried).
5. Voila! You've successfully created 20 mL of a 6.0% solution from your 10% stock solution. Marvel at your liquid-based comedy masterpiece, and before you know it, you'll be the star of the lab.
Remember, laughter is the best medicine for both humans and solutions. Enjoy your creation responsibly and use it for all your future chemistry-related shenanigans!
To make a 20 mL of a 6.0% solution from a stock solution with a concentration of 10%, you will need to follow these steps:
1. Determine the amount of stock solution needed:
Since the concentration of the stock solution is 10% and you want to make a 20 mL solution with a concentration of 6%, you can use the following formula:
Amount of stock solution needed = (Desired concentration / Stock concentration) x Volume of final solution
Plugging in the values:
Amount of stock solution needed = (6% / 10%) x 20 mL
Amount of stock solution needed = 0.6 x 20 mL = 12 mL
Therefore, you will need 12 mL of the stock solution.
2. Measure 12 mL of the stock solution:
Using a graduated cylinder or a pipette, accurately measure out 12 mL of the stock solution.
3. Add a solvent to reach the final volume:
Since you want a final volume of 20 mL, you will need to add a solvent to the measured 12 mL of the stock solution. The solvent can be distilled water or any other appropriate solvent.
Pour the 12 mL of stock solution into a container, and then slowly add the solvent until the total volume reaches 20 mL. You can use a graduated cylinder or a pipette to measure the solvent accurately.
4. Mix thoroughly:
To ensure homogeneity, mix the contents of the container thoroughly. You can do this by gently swirling the container or using a magnetic stirrer.
5. Verify the concentration:
If needed, you can verify the concentration of the final solution using appropriate methods, such as spectrophotometry or titration.
Following these steps, you should be able to make 20 mL of a 6.0% solution from a stock solution with a concentration of 10%.
To make a 20 mL solution with a concentration of 6.0% using a stock solution with a concentration of 10%, you would need to make a dilution. Dilution involves adding a solvent (usually water) to a concentrated solution to lower its concentration.
Here are the steps to follow:
1. Determine the amount of stock solution needed: To find the amount of the 10% stock solution needed, you can use the formula:
volume_stock_solution * concentration_stock_solution = volume_final_solution * concentration_final_solution
Let's plug in the values we know:
volume_stock_solution * 10% = 20 mL * 6.0%
Rearranging the formula to solve for volume_stock_solution:
volume_stock_solution = (20 mL * 6.0%) / 10%
Simplifying the calculation:
volume_stock_solution = (20 mL * 0.06) / 0.10
volume_stock_solution = 12 mL
So, you need to take 12 mL of the 10% stock solution.
2. Add the stock solution to a container: Using a pipette or a measuring cylinder, measure 12 mL of the 10% stock solution.
3. Add the solvent: Since you need a total volume of 20 mL, you will need to add solvent (usually water) to make up the remaining volume. Measure 8 mL of the solvent and add it to the container containing the stock solution.
4. Mix well: Once you have added the stock solution and the solvent, you need to mix them thoroughly to ensure even distribution and achieve the desired concentration. You can gently swirl the container or use a stirring rod to mix the solution.
By following these steps, you will obtain a 20 mL solution with a concentration of 6.0% using the 10% stock solution.
