Lysozyme is an enzyme that cleaves bacterial cell walls. A sample of lysozyme extracted from egg white has a molar mass of 13,930 g. A quantity of 0.100 g of this enzyme is dissolved in 1.80 ×102 g of water at 25°C. Calculate the vapor-pressure lowering, the depression in freezing point, the elevation in boiling point, and the osmotic pressure of this solution. (The vapor pressure of water at 25°C is 23.76 mmHg.) Report each of your answers to 3 significant figures. Vapor-pressure lowering = _____mmHg Depression in freezing point = ___°C Elevation in boiling point = ____°C Osmotic pressure = _____ atm
