Final answer:

To determine the number of mg of NaCl present in a 296 mL sample of a solution with a concentration of 355 ppm NaCl, use the formula mg of NaCl = (ppm/1000000) x volume (mL). Plugging in the values, there are approximately 0.105 mg of NaCl in the 296 mL sample.

Step-by-step explanation:

To determine the number of mg of NaCl present in a 296 mL sample of a solution with a concentration of 355 ppm NaCl, we can use the formula:

mg of NaCl = (ppm/1000000) x volume (mL)

In this case, the ppm is 355, and the volume is 296 mL. Plugging these values into the formula, we get:

mg of NaCl = (355/1000000) x 296

Simplifying the equation, we find that there are approximately 0.105 mg of NaCl in the 296 mL sample.
