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

many liters of water should she add to the glucose to obtain the required solution?
Use g/L
grams of solute
/
liter of solution

0.010 L
0.10 L
3.2L
10. L

Answer 1

its b on edge

Step-by-step explanation:

Answer 2

0.10 L

Step-by-step 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
