Please help me with this question, significant figures
matter
At constant volume, the heat of combustion of a particular compound is –3791.0 kJ/mol. When 1.479 g of this compound (molar mass is 142.16 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 6.637 °C. What is the heat capacity of the calorimeter? heat capacity: kJC

CAN YALL PLEASE HELP ME I HAVE 4 HOURS TO DO THESE!! THANK YOU!! Question 1 A mass of 4 kilograms of air in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 0.3 MPa, T1 = 211°C: Process 1–2: Constant-temperature expansion until the volume is twice the initial volume. Process 2–3: Constant-volume heating until the pressure is again 0.3 MPa. Assuming ideal gas behavior, determine the temperature at state 3, in kelvin. _________________________________________________...
