Answer: 0.05 grams
volume of glucose = 0.500 L
concentration of glucose = 0.100 g/L Amount of glucose in the sample = ?
Recall that the concentration of a solution depends on the amount of solute dissolved in a particular volume of solvent.
I. e Concentration in g/L =
Amount in grams / Volume in liters
0.100 g/L = Amount in grams / 0.500 L
Amount in grams = 0.100 g/L x 0.500 L
= 0.05 grams
Thus, there are 0.05 grams of glucose present in the sample.
