How Do You Make 40% Glucose Solution?
Glucose has the molecular formula C6H12O6, making it a simple sugar. It is the main product of photosynthesis and is used widely used in organisms—including humans—as a source of chemical energy. A glucose solution consists of glucose mixed with a solvent, usually water. Students commonly prepare glucose solutions in classroom laboratories. Determine the desired weight of the glucose solution. This will typically be provided in the instructions for the experiment. For the purposes of this example, assume you want to prepare a 100g glucose solution. Calculate the mass of glucose needed for the solution. Concentration is defined as Mg/Ms = c, where Mg is the mass of the glucose, Ms is the total mass of the solution and c is the concentration. The total mass of the solution is 100g and the concentration is 40 percent, so Mg/Ms = c = Mg/100 = 0.4 –> Mg = (.4)(100) = 40g. You’ll need 40g of glucose to make the solution. Pour the correct amount of water into the beaker. The mass of the
