The atomic mass is determined by the number of protons and neutrons in a atoms for example oxygen has eight protons and neutrons which gives oxygen and atomic mass of 16

Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?
Solving:
Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT
If: ΔT (T final - T initial) = ?
Answer:
<h3>The answer is 3754.33 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 21.7 kg = 21700 g
volume = 5.78 cm³
We have
We have the final answer as
<h3>3754.33 g/cm³</h3>
Hope this helps you
