1) Throughout this question, use relevant information from the Data Booklet. a) The molar enthalpy of solution of the fertilizer, urea (NH2CONH2), is +13.9 kJ/mol. Suppose a certain mass of urea is added to 200.0 mL of water in a simple calorimeter, causing a temperature change from 21.4C to 14.2C. Determine the mass of the urea. (Specific heat capacity of water: 4.18 J/g.C; density of water: 1.00 g/ml) (4)
