Main Goal: Convert the experimental glucose concentration from mM (millimolar) to g/100 mL. Take the 1/100 dilution factor into consideration Molarity will open the doors for you to get to grams. Once at M assume 1L of solution. (Hint: this will help you when converting from M to moles) You will also need to calculate the molar mass of glucose which has the formula C6H12O6 There are 5 steps in total Task 1: Write a step-by-step guide with key words for the students on how to do these calculations. Ensure the steps are clearly written and easy to follow.

Calculate solution concentration in molarity units. A student weighs out 3.23 g of KBr, transfers it to a 125. mL volumetric flask, adds enough water to dissolve the solid and then adds water to the 125 mL mark on the neck of the flask. Calculate the concentration (in molarity units) of potassium bromide in the resulting solution? M Check & Submit Answer Show Approach The concentration of a solute in a solution can be used along with the compound formula to determine the concentration of a specific ionic species in a solution. For example, the concentration of calcium ions and chloride iors in the 0.523 M CAC12 solution is calculated here: (Ca*+] = 0.523 mol CaCl2 1 L 1 mol Ca?+ 1 mol CaCl2 = 0.523 M étv LA hulu
