Question

A glucose solution that is prepared for a patient should have a concentration of 180 g/L. A nurse has 18 g of glucose. How

Answer 1

Answer:

0.10 L

Explanation:

The concentration of glucose  is given as 180 g/L

The mass of glucose is 18 g

• Concentration in g/L is calculated by dividing mass of the solute by the volume of the solution.
• When calculating molarity on the other hand, we divide number of moles of the solute by the volume  of the solution.

• Concentration in g/L = Mass of solute ÷ Volume

Rearranging the formula,

Volume = Mass of the solute ÷ concentration

             = 18 g ÷ 180 g/L

            = 0.10 L

Therefore, volume of water is 0.10 L
