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 mo

scZoUnD [109]

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:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{108\ g}{180.156\ g/mol}$

$Moles= 0.5995\ mol$

Given Volume = 2 L

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

$Molarity=\frac{0.5995}{2}$

<u>Molarity = 0.3 mol/L</u>
