The ingredients contained in grape Kool-Aid can be approximated as: • water (H2O, density = 1.000 g/mL), • sugar (sucrose, solid at room temperature, C12H22O11), • citric acid (solid at room temperature, CeHsO7), and grape flavouring (methyl anthranilate, liquid at room temperature, C8H9NO2, 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).

Question
2. a) 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, CeHsO7), and
grape flavouring (methyl anthranilate, liquid at room temperature, C&H&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).
