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...

A dietitian has been consulted to review the texture modified menu in a LTC facility. The dietitian was also asked to provide recommendations on using outsourced products to include on the texture modified menu. The present non-selective texture modified menu provides 30-35 g of protein and 6,800 - 9200 kJ (1,600 - 2,000 kcal) per day. In addition, residents are offered three between-meal nourishments. The last audit indicated that 40% of the time, residents did not accept the nourishments offer...
