Solutions Lab Report Instructions: Complete all sections of this report and answer all questions in complete sentences for full credit. Solutions Pre-Lab Questions Complete the pre-lab questions to get the values you need for your drink solutions. 1. Calculate the molar mass of powered fruit drink mix, made from sucrose (C 12 H 22 O 11 ). - c = 12.01(12) = 144.012 g/mol - h = 1.008(22) = 22.176 g/mol - o = 16.000 (11) = 175.989 g/mol - 342.177 g/mol 2. Determine the mass of powdered drink mix needed to make a 1.0 M solution of 100 mL. Use molarity = moles of solute (mol) ÷ liters of solution (L) to calculate the amount of drink mix, in moles. Then convert moles to grams using a mole conversion: moles = grams/molar mass - M = mol/liters - mol = M(L) - mol = (1.0M)(.100L) - 0.1 mol - 34.218 g 3. What mass of powdered drink mix is needed to make a 0.5 M solution of 100 mL? 34.218/2 = 17.109G Data Taste Texture Color Control sweet Smooth Light Red 1.0 M without heat sweet & strong Grainy Dark Red 0.5 M without heat Strong and very sweet Smooth Dark Red 1.0 M with heat BiƩersweet Grainy Light Red 0.5 M with heat More sweet than biƩer Smooth Light red 1.0 M with sƟr Strong and sour Very grainy Dark red Unless Otherwise Noted All Content © 2022 Florida Virtual School.

A statement identifying the solubility factors that changed the mixture the most. A statement identifying the solubility factor that changed the mixture the least. Post-Lab Connection Questions Unless Otherwise Noted All Content © 2022 Florida Virtual School. FlexPoint EducaƟon Cloud™ is a trademark of Florida Virtual School. The lab was conducted to determine the differnt factors that influenced the solubility of sucrose in a powdered fruit drink mix: temperature, agitaƟon, and parƟcle size. I found that generally, solubility went up as the temperature increased, although this occasionally produced a biƩer aŌertaste. AgitaƟon, such as in sƟrring, increased the qualiƟes of solubility, making smoother textures. Smaller parƟcles dissolved faster and more fully than larger ones. Temperature had the greatest effect on solubility and changed the mixture the most. The lowest impact was parƟcle size, where changes were not as prominent as those in temperature and agitaƟon. Overall, it turned out that different factors can influence this process of dissoluƟon and characterisƟcs of a soluƟon.
