The ingredients contained in grape Kool-Aid can be approximated as: water (H2O, density = 1.000 g/mL), sugar (sucrose, solid at room temperature, C12H22011), citric acid (solid at room temperature, C6HO7), and grape flavouring (methyl anthranilate, liquid at room temperature, CeH,NO2, density = 1.168 g/mL). (The blue and red dyes used to produce the purple colour are present in such small quantities that they can be ignored.) A sample of grape Kool-aid having a final total volume of 500 mL can be prepared from: 485 mL of water, 32.0 g of sugar, 5.00 g of citric acid, and 3.50 g or grape flavouring. Calculate the molarity and molality of grape flavouring in this mixture (assume that only water is the solvent). Fun fact: methyl anthranilate is also used as a bird repellant (to keep geese away).
