1, Lemonade contains 20% sucrose, 2% salt (NaCl), and 0.5%citric acid (w/v each) in water. Calculate the mole fraction foreach of these components (sucrose, salt, citric acid andwater).
2. 1000 kg of orange juice containing 15% solids is used toprepare orange juice concentrate in two stages. In the first stagethe orange juice is passed through evaporator to remove water. Theproduct from evaporator contains 45% solids. This partiallyconcentrated juice is then fed into a second stage mixer wheresugar is added to the juice in such a way that final solid contentof the concentrate is 55%. Calculate the amount of a) waterremoved, b) sugar added c) final product.
