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- h = 1.008(22) = 22.176- o = 16.000 (11) = 175.989- 342.177 g/mol 2. Determine the mass of powdered drink mix needed to make a 1.0 M solution of 100 mL. M = mol/liters- mol = M(L)- mol = (1.0M)(.100L)- 0.1 mol- 34.218 g 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 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 1.0 M without heat Sweet and strong Grainy Dark red 0.5 M without heat Strong and very sweet Smooth Dark red 1.0 M with heat Bittersweet Sporadically grainy Light red 0.5 M with heat Bittersweet, more sweet Smooth Light red 1.0 M with stir Strong and sour Very grainy Dark red 0.5 M with stir Strong and sour, but kinda sweet Smooth Dark red 1.0 M without stir Sour Very grainy Light red 0.5 M without stir Bittersweet Smooth Light red 1.0 M with sugar Sweet Smooth Very dark red 0.5 M with sugar Dull Smooth Very dark red 1.0 M w sugar cubes Sweet Smooth Very dark red Unless Otherwise Noted All Content © 2022 Florida Virtual School.
