Hi.
You can calculate mass percent by dividing the mass by the total mass of the compound & multiplying by 100.
28.8 ÷ (171.2 + 28.8) = 0.144
0.144 · 100 = 14.4
I believe the mass percent of the hydrogen in the compound is 14.4%

The small particles are known as protiens
The heat released : -110560.632 J
<h3>Further explanation</h3>
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
<h3>Known</h3>
m =465 g
c water = 4.186 J/gram °C
∆T = temperature difference = 18.2 - 75 = - 56.8 °C
Then the heat :
