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?

Answer: 0.05 grams

Explanation:

Given that:

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.
