if 500g of water is added to 75g of 25% nacl solution, what is the percent solution by mass of nacl in the diluted solution

Answers

Percent solution of NaCl = 3.26%

Step 1: Determine the mass of NaCl in the initial solution
The initial solution is 25% NaCl, which means there are 25 grams of NaCl for every 100 grams of solution. To find the mass of NaCl in the 75g solution, use this proportion:

(25g NaCl / 100g solution) = (x / 75g solution)

Solve for x:

x = (25g NaCl * 75g solution) / 100g solution
x = 18.75g NaCl

Step 2: Determine the total mass of the diluted solution
Add the mass of water (500g) to the mass of the initial solution (75g):

Total mass = 500g water + 75g solution = 575g diluted solution

Step 3: Calculate the percentage of NaCl in the diluted solution
Use the mass of NaCl from Step 1 and the total mass of the diluted solution from Step 2 to find the percentage by mass:

Percentage = (Mass of NaCl / Total mass of diluted solution) * 100
Percentage = (18.75g NaCl / 575g diluted solution) * 100
Percentage ≈ 3.26%

The percent solution by mass of NaCl in the diluted solution is approximately 3.26%.

Answers

If a reaction system has come to equilibrium, the concentration of products can be increased by applying Le Châtelier’s principle. The answer is letter C. The statements "only if it is not reversible", "only if the temperature is low enough" and "under no circumstances" do not answer the question above.
