Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Osmotic pressure can be very useful for estimating the molecular weights of macromolecules for whom a molecular formula may not be available as it can provide greater precision in the measurement. (a) 1.364 g of a protein with molecular mass 1.78 × 104 g/mol is dissolved in enough water to create 100.0 mL of solution at 298 K. What would be the expected osmotic pressure (in bars) of this solution? (b) If 1.853 g of a protein are dissolved in enough water to make up 100.0 mL of solution at 298 K, then the osmotic pressure is observed to be 2.521 torr (3.361 × 10-³ bar). What is the molar mass (g/mol) of the protein?

The mole fraction of sodium chloride, NaCl, in a saturated aqueous solution is 0,220. (a) What is the molality (molal concentration) of this solution? (b) What is the molarity (molar concentration) of this solution if it has a density of 1,150 g.cm–3? (c) What is the mass percentage NaCl in the solution? Which of the following liquids are likely to be miscible with water: 1-propanol (CH3CH2CH2OH), carbon tetrachloride (CCl4), hexane (C6H14), and acetic acid (CH3CO2H)? Motivate your choice(s) using your knowledge of intermolecular forces. The vapor pressure of pure water at 45 °C is 71,9 mm Hg. What is the vapor pressure of a mixture of 21,0 g sucrose (C12H22O11, molar mass 342,3 g/mol) and 79,0 g water?
