To solve this problem, we need to understand that a 4.00% NaOH solution by mass means that there are 4.00 g of NaOH in every 100 g of solution.

Step 1: Set up the proportion to find the mass of the solution.
The proportion is 4.00 g NaOH / 100 g solution = 15.0 g NaOH / x g solution.

Step 2: Solve for x.
Cross-multiplying gives us 4.00x = 1500.
Dividing both sides by 4.00 gives us x = 375 g.

So, 375 g of a 4.00% NaOH solution contains 15.0 g of NaOH.
