How many grams are present in 600 mL of a 25% solution?

To determine how many grams are present in 600 mL of a 25% solution, it's important to understand the definition of percentage concentration. A 25% solution means that there are 25 grams of solute for every 100 mL of solution.

First, we can set up a proportion based on the given percentage:

1. Calculate the amount of solute in grams in 600 mL using the percentage.

Given that there are 25 grams in 100 mL, we can find out how many grams are in 600 mL as follows:

• If 100 mL corresponds to 25 grams, then 600 mL will contain a proportional amount of solute.

Using the formula:

[ \text{grams of solute} = \left(\frac{25 \text{ grams}}{100 \text{ mL}}\right) \times 600 \text{ mL} ]

2. Performing the calculation:

[ \text{grams of solute} = 25 \times \left(\frac{600}{100}\right) = 25 \times 6 = 150 \text{ grams} ]

Thus, in 600 mL of a 25% solution
