(b) For a correct description of step 1: Accept one of the following: Use the spatula, balance, and weighing paper to measure out exactly 0.169 g of CH 3 NH 3 Cl( s ) . Use the balance to weigh out the mass of solid in part (a). Assuming that no heat energy is lost from the calorimeter and given that the calorimeter has a negligible heat capacity, the sum of the heat of dissolution, qsoln and the change in heat energy of the urea-water mixture must equal zero. qsoln + mcΔT = 0. ⇒. qsoln = − mcΔT. msoln = 5.13 g + 91.95 g = 97.08 g. Include units with your answer. q = mc T = (110.0 g)(4.18 J/(g·°C))(35.6°C 15.0°C) 1 point is earned for the correct setup. 1 point is earned for the = 9,470 J = 9.47 kJ correct answer with units.
