Как приготовить 200 гр раствора содержащего 10% соли

Answer 1

1).200*0,1=20(г)-соли; 2).200-20=180(г)-воды.

Answer 2

Preparing a 10% Salt Solution

To prepare a 200g solution containing 10% salt, you can follow these steps:

1. Calculate the Amount of Salt Needed: - To make a 10% salt solution, you'll need to use the formula: ``` Amount of salt = (Percentage of salt / 100) * Total solution mass ``` - Substituting the values, we get: ``` Amount of salt = (10 / 100) * 200g = 20g ``` - So, you'll need 20g of salt.

2. Dissolve the Salt: - Measure out 20g of salt. - Add the salt to a container. - Gradually add water while stirring until the total mass of the solution reaches 200g.

3. Mix Thoroughly: - Stir the solution thoroughly to ensure the salt is completely dissolved.

4. Verify the Solution: - Use a scale to verify that the total mass of the solution is 200g.

5. Final Check: - Double-check the concentration using a hydrometer or refractometer if available.

This process will result in a 200g solution containing 10% salt.
