Chem Exam: Types of Calculation Questions & Answers 100% Verified 
Calorimetry Calculations: 
1. 2.50 kJ of energy changes the temperature of a sample of lead by 8.52 degrees C. What is the mass of 
the sample? - ANS-Q = mcΔT 
m=Qc/Δt 
m = 2500/0.13(8.52) 
= 2.3×103 g 
2. 950.3 J of energy is removed from 28.5 g of water at 80.3 degrees C. What is the final temperature? - 
ANS-Q = mcΔT 
−950.3 = 28.5(4.18)(T2 − 80.3) 
T2 = −950.3/(28.5)(4.18) + 80.3 
= 72.3O C 
3. A 30.56 g sample...
