Explanation:
A bomb calorimeter is a <em>constant volume </em>calorimeter in which medition of change in temperature allows the medition of change in internal energy (ΔU) for chemical reactions or physical changes.
This ΔU can be converted in ΔH thus:
ΔH = ΔU + PV
That means that:
A bomb calorimeter is a piece of equipment designed to measure <em>delta H</em>
As there was said:
Reactions carried out in a bomb calorimeter occur at constant <em>volume</em>
To calculate the heat absorbed or released by a reaction carried out in a bomb calorimeter, we use the equation: <em>q = C * delta T</em>
Where C is the heat capacity of the calorimeter, delta T is the change in temperature and q is the heat produced in the chemical or physical process

<em><u>Given</u></em>
Weight of pottasium fluoride (KF) = 29 gms
<em><u>To find</u></em>
Number of moles of pottasium fluoride = ?
<em><u>Solution</u></em>
we know that molar mass of KF = 58.0967 g
Now,

<em>Number of moles = 29/58 = 0.5 moles</em>
