how much salt must be added to how much water to create 10ml of a
10% saline solution.
volume=10ml
mass=11grams.
add 1 gram salt to 10ml water.
Well, I don't want to be salty, but here's the scoop! To make a 10% saline solution, you need to add 1 part salt to 9 parts water. So in this case, you'll need to add 1 mL of salt to 9 mL of water to create your delightful 10 mL of saline solution. Just remember, no tears in the lab or you might end up with a solution that's too salty to handle!
To create a 10% saline solution with a total volume of 10ml, we need to calculate the amount of salt and water needed.
Step 1: Convert the desired concentration to a decimal.
A 10% solution means that 10% of the total volume will be salt. So, 10% is equivalent to 0.1 in decimal form.
Step 2: Calculate the amount of salt needed.
Since 10% of the total volume should be salt, the amount of salt needed is 0.1 multiplied by 10ml, which is 1ml of salt.
Step 3: Calculate the amount of water needed.
To determine the amount of water needed, subtract the volume of salt from the total volume.
10ml total volume - 1ml salt = 9ml water.
In summary, to create a 10ml 10% saline solution, you would need to add 1ml of salt to 9ml of water.
To determine how much salt must be added to how much water to create a 10% saline solution, you'll need to know the desired concentration (10%) and the volume of the final solution (10 mL).
Step 1: Calculate the amount of salt needed:
Since 10% saline solution means there is 10 grams of salt in 100 mL of solution, you can set up a proportion to find the amount of salt needed for 10 mL of solution.
10 g/100 mL = x/10 mL
Cross-multiplying the proportion gives:
100x = 10 * 10
100x = 100
Dividing both sides by 100 gives:
x = 1
This means you would need 1 gram of salt for a 10% saline solution with a volume of 10 mL.
Step 2: Determine the amount of water needed:
Since the total volume of the solution is 10 mL and you're adding 1 g of salt, the remaining volume would be water. Therefore, the required amount of water will be:
Volume of water = Total volume - Volume of salt
Volume of water = 10 mL - 0.10 mL (since 1 g of salt is equivalent to 1 mL)
Volume of water = 9.9 mL
So, to create a 10 mL 10% saline solution, you would need to add 1 gram of salt to 9.9 mL of water. Keep in mind that this calculation assumes the density of salt is equal to that of water for simplicity purposes.
