Final answer:

To calculate ppt, which is grams of solute per kilogram of solvent, 0.5 grams of sugar in 1 liter of solution is equivalent to 0.5 ppt. Therefore, the answer is b) 0.5 ppt.

Step-by-step explanation:

To calculate the concentration of sugar in parts per thousand (ppt) when there are 0.5 grams of sugar per 1 liter of solution, you can use the definition of ppt which is the grams of solute per kilogram of solvent. Since the solution has a volume of 1 liter, which is equivalent to 1 kilogram for water (the density of pure water is approximately 1 g/mL), the calculation is straightforward:

0.5 grams sugar / 1 kilogram solution = 0.5 grams sugar / 1000 grams solution

Multiply the result by 1000 to convert to ppt:

0.5 grams sugar / 1000 grams solution × 1000 = 0.5 ppt

Therefore, the correct answer is b) 0.5 ppt.
