1. What volume (in mL) of a beverage that is 10.5% by mass ofsucrose (C12H22O11) contains 78.5 g of sucrose (Density of the solution 1.04 g/mL).
2. A solution is prepared by dissolving 17.2 g of ethylene glycol(C2H6O2, MW: 62.07 g/mol) in 0.500 kg of water. The final volume of the solution is 515 mL.Calculate (a) molarity, (b) molarity, (c) percent by mass, (d) mole fraction.
3. What is the molarity of a 6.55% (m/m) glucose solution (C6H12O6,MW: 180.16 g/mol) (The density of the solution is 1.03 g/mL).
