(1) Haemoglobin transports oxygen from the lungs to the rest of the body. One molecule of haemoglobin combines with four molecules of oxygen. If 0.01 g of haemoglobin combines with 1.53 cm of oxygen at 37 C and 0.987 kPa, what is the molar mass of haemoglobin? (2) Carbon disulfide, CS2, burns in air to produce carbon dioxide, CO2, and sulfur dioxide, SO2. The standard enthalpy of combustion of CS2 is - 1075 kJ molt, that for Cis-394 kJ mor' and that for Sis -297 kJ mol? What is the standard enthalpy of formation of CS2? Explain any laws used to determine your
