The value with the fewest significant figures is "27.0 g" and "51.0°C" (both have three), so your answer should be rounded to three significant figures: 5760 J . calorimetry worksheet 2 answers chemsheets

q = mc∆T. m = 150. q = 150 x 4.18 x 45.5 = 28530 J. ∆H = q / mol. moles of propane = mass / Mr. = 1.00 / 58.0 = 0.01724. ∆H = –28. Brentford School for Girls Thermodynamics Qs With First Part of Answers PDF - Scribd 10 Jul 2012 —

Experimental results in these worksheets are often significantly lower than theoretical values (e.g., Data Book values) due to: to the surroundings or the calorimeter itself. Incomplete combustion of the fuel (e.g., soot formation). Evaporation of the fuel from the wick before/after weighing. Non-standard conditions (reactions not occurring at Course Hero

The heat of combustion of sucrose is -20.0 kJ/g or -6846 kJ/mol (Literature value is -5640 kJ/mol, showing the need for calibrated equipment). How much heat is required to raise the temperature of 50

The worksheet focuses on advanced enthalpy calculations, specifically calculating standard enthalpy changes ( ΔHcap delta cap H
