What is the molarity of an intravenous glucose solution prepared from 108 g of glucose in 2.0 L of solution? 0.018 mol/L 0.30 mol/L 0.60 mol/L 2.2 x 102 mol/L

Respuesta :

Answer:

0.30 mol/L

Explanation:

Mass = 108 g

Molar mass of glucose = 180.156 g/mol

The formula for the calculation of moles is shown below:

[tex]moles = \frac{Mass\ taken}{Molar\ mass}[/tex]

Thus,

[tex]Moles= \frac{108\ g}{180.156\ g/mol}[/tex]

[tex]Moles= 0.5995\ mol[/tex]

Given Volume = 2 L

[tex]Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}[/tex]

[tex]Molarity=\frac{0.5995}{2}[/tex]

Molarity = 0.3 mol/L
