How many grams of NaCl are presented in 250g of salt solution containing 9% NaCl?

9% NaCl(Iassume that is mass percent) means 9 g NaCl/100 g solution.

You have 250 g solution; therefore,
9 x (250/100) = ? g in 250 g solution.

To find out how many grams of NaCl are present in 250 grams of a 9% salt solution, follow these steps:

Step 1: Calculate the amount of NaCl in the salt solution.
9% of 250 grams = (9/100) * 250 = 22.5 grams

Therefore, there are 22.5 grams of NaCl presented in 250 grams of the salt solution.

To find the number of grams of NaCl in the salt solution, you can use the following steps:

1. Start by calculating the amount of NaCl in the solution. The concentration of NaCl is given as 9%, which means that 9g of NaCl is present in every 100g of the solution.

2. Determine the amount of solution you have, which is 250g.

3. Use the following formula to calculate the grams of NaCl in the solution:

(NaCl concentration / 100) * amount of solution

In this case, it would be:

(9 / 100) * 250

4. Performing the calculation:

(0.09) * 250 = 22.5

The salt solution containing 9% NaCl has 22.5 grams of NaCl.
