What is the concentration of a solution with 5 grams of solute in 200 mL of solution?

To determine the concentration of a solution, the formula used is:

[ \text{Concentration (g/L)} = \frac{\text{Mass of solute (g)}}{\text{Volume of solution (L)}} ]

In this case, you have 5 grams of solute and 200 mL of solution. First, you need to convert the volume from milliliters to liters, since the concentration is typically expressed in grams per liter. There are 1000 mL in 1 L, so:

[ 200 , \text{mL} = \frac{200}{1000} , \text{L} = 0.2 , \text{L} ]

Now you can apply the concentration formula:

[ \text{Concentration} = \frac{5 , \text{g}}{0.2 , \text{L}} ]

Calculating this gives:

[ \text{Concentration} = 25 , \text{g/L} ]

Therefore, the concentration of the solution is 25 g/L, which aligns with the correct answer. Understanding this process is essential in medical and scientific applications as it helps quantify how much of
