What is the amount in grams of table salt that is present in 500.0 g of total solution of salt water. Concentration of this solution is 15% (m/m).

To find the amount of table salt in the solution, you need to use the given mass/mass percent concentration. This concentration means that there are 15 g of table salt in every 100 g of solution.

Here are the steps to find the solution:

1. Understand that the 15% (m/m) concentration means that in every 100 g of solution, 15 g is table salt.
2. You have 500 g of solution. To find out how much of that is table salt, set up a proportion: (15 g table salt / 100 g solution) = (x g table salt / 500 g solution).
3. Solve for x, which represents the amount of table salt in 500 g of solution. Cross-multiply to get: 15 g table salt * 500 g solution = 100 g solution * x g table salt.
4. Simplify to get: 7500 g table salt = 100x g table salt.
5. Divide both sides by 100 to solve for x: x = 75 g table salt.

So, there are 75 g of table salt in 500 g of the solution.
