A sample of a glucose solution has a volume of 0.500 L. The concentration of glucose in the solution is 0.100 g/L. How many grams of glucose are present in the sample?

Multiply the concentration by the volume: 0.100 g/L × 0.500 L = 0.0500 g. The liters cancel, leaving grams of glucose. Therefore, the sample contains 0.0500 g, choice A.
