how much sodium chloride and how much water would you need to prepared a 5.00kg of an aqueous solution that is 10.0% NaCl by mass?

%NaCl = (mass NaCl/100 g soln)*100

(x g NaCl/5,000 g soln)*100 = 10
Solve for x.

I suppose I answered only half the question. I solved for x to obtain 500 g NaCl but you need to confirm that.

Then 5,000 g H2O - 500 g NaCl = 4.5 kg.

Check it to make sure that's a 1-% solution.
(500 g NaCl/4500 gH2O+500 gNaCl)*100 = ??%
(500/5,000)*100 = (50000/5000) = 10%
check out. Check me out on that.

To calculate the amount of sodium chloride and water needed to prepare a 5.00kg solution that is 10.0% NaCl by mass, we can follow these steps:

Step 1: Determine the mass of NaCl required:
- 10.0% of 5.00kg is equivalent to 0.10 * 5.00kg = 0.50kg.

Step 2: Determine the mass of water required:
- The total mass of the solution is 5.00kg, and the mass of NaCl is 0.50kg. Therefore, the mass of water is 5.00kg - 0.50kg = 4.50kg.

Therefore, you would need 0.50kg of sodium chloride and 4.50kg of water to prepare a 5.00kg aqueous solution that is 10.0% NaCl by mass.

To determine how much sodium chloride (NaCl) and water you would need to prepare a 5.00 kg solution that is 10.0% NaCl by mass, you can follow these steps:

Step 1: Understand the problem.
- The goal is to prepare a solution that is 10.0% NaCl by mass.
- The total mass of the solution is given as 5.00 kg.

Step 2: Calculate the mass of NaCl needed.
- To calculate the mass of NaCl needed, we need to determine what 10% of the total mass (5.00 kg) would be.
- 10% of 5.00 kg = 10/100 * 5.00 kg = 0.50 kg.

Step 3: Calculate the mass of water needed.
- To find the mass of water needed, subtract the mass of NaCl from the total mass of the solution.
- Mass of water = Total mass - Mass of NaCl
- Mass of water = 5.00 kg - 0.50 kg = 4.50 kg.

So, to prepare a 5.00 kg solution that is 10.0% NaCl by mass, you would need 0.50 kg of NaCl and 4.50 kg of water.
