Glucose (dextrose) solutions are given intravenously to patients combined with other drugs. Different concentrations of glucose are used for different purposes. A 5% (w/w) glucose solution is commonly used. The density of this solution is 1.02 g `mL^(-1)`.
What is the molality of the solution?

To find the molality of a 5% (w/w) glucose solution, we can follow these steps: ### Step 1: Understand the Composition of the Solution A 5% (w/w) glucose solution means that there are 5 grams of glucose in every 100 grams of the solution. ### Step 2: Calculate the Mass of the Solvent Since the total mass of the solution is 100 grams and it contains 5 grams of glucose, the mass of the solvent (water) can be calculated as follows: \[ ...
