Answer:
176984.38J
Explanation:
E = mC∆T
Where E is the energy in joules
M is the mass of water
C is the specific heat capacity of water =4.184J/g°C
It is known that it will take 4.184J of energy to change the temperature of water by one degree Celsius.
∆T = 98.6°c - 5.4°c
= 93.2°c
∆H = 454.3g × 4.18J/g°C × 93.2°c
= 176984.3768
176984.38J

Answer:
1.61%.
Explanation:
The following data were obtained from the question:
Measured mass = 3.15 g.
Actual mass = 3.10 g
Percentage error =.?
The percentage error of the group can be obtained by using the following equation below:
Percentage error = |Actual mass – Measured mass| / Actual mass × 100
Percentage error = |3.10 – 3.15| /3.10 × 100
Percentage error = 0.05/3.1 × 100
Percentage error = 5/3.1
Percentage error = 1.61%
Therefore, the percentage error of the group is 1.61%.
